Abstract:

Von Neumann proved the minimax theorem (existence of a saddle-point solution to 2 person, zero sum games) in 1928. While his second article on the minimax theorem, stating the proof, has long been translated from German, his first announcement of his result (communicated in French to the Academy of Sciences in Paris by Borel, who had posed the problem settled by Von Neumann's proof) is translated here for the first time. The proof presented by Von Neumann and Morgenstern (1944) is not Von Neumann's rather involved proof of 1928, but is based on what they called "The Theorem of the Alternative for Matrices" which is in essence a reformulation of an elegant and elementary result by Borel's student Jean Ville in 1938. Ville's argument was the first to bring to light the simplifying role of convexity and to highlight the connection between the existence of minimax and the solvability of systems of linear inequalities. It by-passes nontrivial topological fixed point arguments and allows the treatment of minimax by simpler geometric methods. This approach has inspired a number of seminal contributions in convex analysis including fixed point and coincidence theory for set-valued mappings. Ville's contributions are discussed briefly and von Neuman's original communication, Ville's note, and Borel's commentary on it are translated here for the first time.

Abstract:

Iver Neumann has been an inter-disciplinary entrepreneur for political science in Norway. For Neumann, interdisciplinarity has been coupled with an understanding of politics as the search for meaning and identity. These features are well-developed in European political science, particularly within the field of international relations, but they are more rarely encountered in Norway. This brief article provides a sketch of political science as it evolved and matured in its Norwegian incarnation. In situating Iver Neumann within the discipline, I emphasise his international and eclectic orientation. The personal, national and international meet in Neumann’s works, as do popular culture and politics.

Abstract:

The ArgumentCarl Gottfried Neumann was born in Königsberg, Prussia, in 1832 and died in Leipzig in 1925. His father was the physicist Franz Neumann (1798–1895), notable for his contributions not only to the study of electricity and magnetism but also to the development of physics education in nineteenth-century Germany. Carl Neumann studied at the University of Königsberg and received his doctorate in 1855 with a work on the application of elliptic integrals to mechanics (Neumann 1856). In 1858 he became Privatdozent, and in 1863 Professor of Mathematics at Halle. Later that same year he moved to Basel, and in 1865 he became Ordinary Professor of Mathematics at Tübingen. Finally in 1868 he was appointed Professor of Mathematics at Leipzig, a post he held until he retired in 1911; of the two mathematics professorships at Leipzig, this was the one formerly held by F. A. Möbius, and it was officially devoted to “the higher mathematics, especially physics” (quoted in Jungnickel and McCormmach 1986, 1:181). So Neumann's academic career, along with his role as one of the founding editors of the Mathematische Annalen beginning in 1869, can be seen as reflecting the enormous advance in mathematical sophistication that German physics underwent in the latter part of the nineteenth century.

Abstract:

AbstractAround 1989, a striking letter written in March 1956 from Kurt Gödel to John von Neumann came to light. It poses some problems about the complexity of algorithms; in particular, it asks a question that can be seen as the first formulation of the P = ? NP question. This paper discusses some of the background to this letter, including von Neumann's own ideas on complexity theory. Von Neumann had already raised explicit questions about the complexity of Tarski's decision procedure for elementary algebra and geometry in a letter of 1949 to J. C. C. McKinsey. The paper concludes with a discussion of why theoretical computer science did not emerge as a separate discipline until the 1960s.

Abstract:

This paper analyzes the characteristics and academic value of History of the Pirates who Infested the China Sea from 1807 to 1810 translated by German Orientalist Karl Friedrich Neumann. The original author of this book is JingHaiFunJi, published in Guangzhou, China in 1830. The book recorded the rise and fall of pirates in Guangdong who were active in the South China Sea. Karl Friedrich Neumann, a translator, purchased the original book in Guangzhou, China in the fall of 1830 and began translating it, and published a translation in London, the following year in 1831. In the early 19th century, the Qing Dynasty maintained a very closed foreign policy and was never friendly to foreigners. In this era, Neumann's purchase of the original book and publication of the domain proceeded surprisingly quickly. Neumann's domain was not simply a translation of Chinese into English, but was reorganized to suit the tastes of European readers. In addition, detailed explanations and rich annotations were attached to make it easier for readers who are unfamiliar with Chinese history, culture, and language to understand, making it different from the original text. It also contains the author's sharp views and insights into China's reality and China's complex history, culture, and politics, which the orientalist Neumann witnessed firsthand, allowing foreign scholars to grasp the view of China in the 19th century. Therefore, in this paper, we would like to analyze History of the Pirates who Infested the China Sea from 1807 to 1810 translated by Karl Friedrich Neumann to examine its characteristics and academic significance.

Abstract:

The process of the canonization and beatification of John Nepomucene Neumann began in 1886 in the Archdiocese of Philadelphia and the Diocese of Budweis. His canonization was completed in 1977. The study presents the as yet uncharted topic of the informative process in the Diocese of Budweis in 1886-1888, including a follow-up examination of John Nepomucene Neumann’s written estate in 1891 and other activities and events related to the Neumann’s process of beatification and canonization up to the beginning of the so-called Apostolic process in December 1896. This study seeks to describe in more detail the ecclesiastical legal process of the whole case; in addition to the context, it seeks to show in a broader horizon the so-called second life of John Nepomucene Neumann in the Diocese of Budweis, which was associated with the spread of his spiritual legacy.

The recent discovery of new families of special functions, orthogonal on <em>F</em>, makes it possible to consider not only the Dirichlet or Neumann boundary value problems on <em>F</em>, but also the mixed boundary value problem which is a mixture of Dirichlet and Neumann type, ie. on some parts of the boundary of <em>F</em> a Dirichlet condition is fulfilled and on the other Neumann’s works.

Abstract:

Semigroup presentations have been studied over a long period, usually as a means of providing examples of semigroups. In 1967 B. H. Neumann introduced an enumeration method for finitely presented semigroups analogous to the Todd–Coxeter coset enumeration process for groups. A proof of Neumann's enumeration method was given by Jura in 1978.In Section 3 of this paper we describe a machine implementation of a semigroup enumeration algorithm based on that of Neumann. In Section 2 we examine certain semigroup presentations, motivated by the fact that the corresponding group presentation has yielded interesting groups. The theorems, although proved algebraically, were suggested by the semigroup enumeration program.

Abstract:

I presume that many of you will be surprised to learn that John von Neumann, a great mathematician, and a remarkable man, had even a passing interest in materials science since his name is usually associated with work in function theory, mathematical logic, the mathematical foundations of quantum mechanics, game theory, and of course with the development of computer logic. Actually, he was deeply interested in the evolution of materials science and technology, and he played an important role in giving prominence to materials science at a critical time in its evolution. But first let me tell you a little about his life.John von Neumann was born in Budapest, Hungary, in 1903 into a prominent business family. His mathematical genius was recognized early by his high school teacher, Lázsló Ratz, who insisted that he receive special tutoring since mathematical geniuses tend to flower early. He became a close and, indeed, a lifetime friend of a slightly older fellow student, Eugene Wigner, who was inspired by the same mathematics teacher. The two of them frequently wandered home together after school, with von Neumann providing a tutorial on some aspect of mathematics while Wigner, who had a comparably brilliant mind, absorbed everything. The two students had different personalities, but shared a great love of mathematics.Von Neumann was never a narrow genius. He soaked up knowledge of all kinds rapidly and was exposed to much because the von Neumann family dinner gatherings were devoted to discussions of technical, historical and cultural affairs, as well as business. This great versatility in interests was a characteristic trademark of von Neumann‘s entire life.

Spectral problems are considered which appear in description of small transversal vibrations of Stieltjes strings. It is shown that the eigenvalues of the Neumann-Neumann problem, i.e. the problem with the Neumann conditions at both ends of the string interlace with the union of the spectra of the Neumann-Dirichlet problems, i.e. problems with the Neumann condition at one end and Dirichlet condition at the other end on two parts of the string. It is shown that the spectrum of Neumann-Neumann problem on the whole string, the spectrum of Neumann-Dirichlet problem on the left part of the string, all but one eigenvalues of the Neumann-Dirichlet problem on the right part of the string and total masses of the parts uniquely determine the masses and the intervals between them.

We are studying numerically the problem of generation and propagation of long-crested gravity waves in a tank containing an incompressible inviscid homogeneous fluid initially at rest with a horizontal free surface of finite extent and of infinite depth. A nonorthogonal curvilinear coordinate system, which follows the free surface, is constructed and the full nonlinear kinematic and dynamic free surface boundary conditions are utilized in the algorithm. “Wavemakers” are modeled using both the Dirichlet and Neumann lateral boundary conditions and a full comparison is given. Overall, the Dirichlet model was more stable than the Neumann model, with an upper limit steepness S=2A/λ of 0.08 using good resolution compared with the Neumann’s maximum of 0.05.

Abstract:

A Murray-von Neumann algebra is the algebra of operators affiliated with a finite von Neumann algebra. In this article, we study derivations of Murray-von Neumann algebras and their properties. We show that the "extended derivations" of a Murray-von Neumann algebra, those that map the associated finite von Neumann algebra into itself, are inner. In particular, we prove that the only derivation that maps a Murray-von Neumann algebra associated with a von Neumann algebra of type ${\rm II}_1$ into that von Neumann algebra is 0. This result is an extension, in two ways, of Singer's seminal result answering a question of Kaplansky, as applied to von Neumann algebras: the algebra may be non-commutative and contain unbounded elements. In another sense, as we indicate in the introduction, all the derivation results including ours extend what Singer's result says, that the derivation is the 0-mapping, numerically in our main theorem and cohomologically in our theorem on extended derivations. The cohomology in this case is the Hochschild cohomology for associative algebras.

Full text

Abstract:

The paper compares the von Neumann model with the approach to the theory of value and distribution of the classical economists on the one hand and that of the neoclassical economists on the other. It is shown that all salient features of the von Neumann model are classical in spirit: its long-period method; its analytical structure revolving around the concept of the surplus product, the latter's appropriation in the form of interest and its use for the purpose of accumulation; and its constitutive aspects. While the von Neumann model focuses attention exclusively on the problem of reproducibility, in neoclassical theory the problem of scarcity assumes centre stage of the analysis. The paper concludes with a remark on a proposition by Arrow and Debreu in their seminal 1954 paper. They contended that their assumption, according to which each and every agent is possessed of an endowment of goods such that he or she can survive under any circumstances whatsoever plays the same role as von Neumann's assumption that each and every commodity enters or exits each and every process of production. It is argued that this proposition cannot be sustained.

Abstract:

It is known that the spectrum of the spectral Sturm-Liouville problem on an equilateral tree with (generalized) Neumann's conditions at all vertices uniquely determines the potentials on the edges in the unperturbed case, i.e. case of the zero potentials on the edges (Ambarzumian's theorem). This case is exceptional, and in general case (when the Dirichlet conditions are imposed at some of the pendant vertices) even two spectra of spectral problems do not determine uniquely the potentials on the edges. We consider the spectral Sturm-Liouville problem on an equilateral tree rooted at its pendant vertex with (generalized) Neumann conditions at all vertices except of the root and the Dirichlet condition at the root. In this case Ambarzumian's theorem can't be applied. We show that if the spectrum of this problem is unperturbed, the spectrum of the Neumann-Dirichlet problem on the root edge is also unperturbed and the spectra of the problems on the complimentary subtrees with (generalized) Neumann conditions at all vertices except the subtrees' roots and the Dirichlet condition at the subtrees' roots are unperturbed then the potential on each edge of the tree is 0 almost everywhere.

This paper deals with second-order differential pencils with a fixed frozen argument on a finite interval. We obtain the trace formulae under four boundary conditions: Dirichlet–Dirichlet, Neumann–Neumann, Dirichlet–Neumann, Neumann–Dirichlet. Although the boundary conditions and the corresponding asymptotic behaviour of the eigenvalues are different, the trace formulae have the same form which reveals the impact of the frozen argument.

Abstract:

As an alternative to nodal domains in the usual sense, we propose a partition of the domain of a real-valued eigenfunction in by trajectories of the gradient, linking saddle points to extrema. Its most elementary properties are listed and exemplified. The main point is that the problem of avoided crossings is largely eliminated.
