Résumé :

Let A be a C∗-algebra with stable rank one and real rank zero. In this paper, it is shown that the usual distance dU defined on the approximate unitary equivalence classes (or unitary orbits) of the positive elements in A is equal to the distance dW defined on morphisms from Cuntz semigroup of C0(0,1] to the Cuntz semigrout of A.

Résumé :

AbstractWe study certain symplectic quotients of n-fold products of complex projective m-space by the unitary group acting diagonally. After studying nonemptiness and smoothness of these quotients we construct the action-angle variables, defined on an open dense subset, of an integrable Hamiltonian system. The semiclassical quantization of this system reporduces formulas from the representation theory of the unitary group.

Résumé :

We generalize bounds of Liu–Wan–Xiao for slopes in eigencurves for definite unitary groups of rank $2$ to slopes in eigenvarieties for definite unitary groups of any rank. We show that for a definite unitary group of rank $n$ , the Newton polygon of the characteristic power series of the $U_p$ Hecke operator has exact growth rate $x^{1+2/{n(n-1)}}$ , times a constant proportional to the distance of the weight from the boundary of weight space. The proof goes through the classification of forms associated to principal series representations. We also give a consequence for the geometry of these

Résumé :

Discusses certain one-parameter subgroups of the low-rank unitary groups called root subgroups. Unitary groups also have representations of Lie type which means they consist of transformations that act as automorphisms of an underlying Lie algebra, in this case the special linear algebra. Exploring this definition of the unitary groups, we find a correlation, via exponentiation, to the basis elements of Lie algebra.

Résumé :

Within the fields of electoral studies and legislative politics, the interest of this study is the Brazilian electoral system and the unity of the parties it produces. Specifically, I ask how post-electoral intraparty rank affects party unity. I determine post-electoral intraparty rank by comparing deputies’ vote share of the total national vote count. By compiling a database of 48 roll-call votes of 37 Federal Deputies from São Paulo, I compare how often the deputies toe the party line to their vote share. I also test for the geographical concentration of votes in cases where I find it relev

This article focuses on the use of the orthogonal polynomial method for computing correlation functions, cluster functions, gap probability, Janossy density, and spacing distributions for the eigenvalues of matrix ensembles with unitary-invariant probability law. It first considers the classical families of orthogonal polynomials (Hermite, Laguerre, and Jacobi) and some corresponding unitary ensembles before discussing the statistical properties of N-tuples of real numbers. It then reviews the definitions of basic statistical quantities and demonstrates how their distributions can be made expl

Résumé :

What does spirituality mean in Judaism? What is prayer and does it work? Prayer is a vital concern in Judaism, and one of the major forms in which spirituality is expressed. Equal in rank, or perhaps even higher, is learning. ‘The spiritual life—prayer, meditation, Torah’ considers the place of spirituality in Jewish worship. The most universal, accessible, and distinctive form of Jewish spirituality is Torah study. Learning the Torah is an expression of love that spans over generations. It is a unity of souls. It unites those who hand it down with those who receive it.

Résumé :

This chapter clarifies how the impulse to close ranks raised concerns about the prioritizing of the collective over the individual. Black collectivity is expressed as kinship in the nationalist imagination, so there is an overriding anxiety about metaphors of family, which assume an intimacy or affiliation that might not be present. The chapter then examines texts informed by nationalism that challenge this investment in kinship. These include John A. Williams's Black Arts historical novel The Man Who Cried I Am (1967), Alice Walker's debut novel The Third Life of Grange Copeland (1970), and G

Résumé :

This chapter tracks how artists inhabit the subjective space of whiteness as a closing ranks move. This idea may seem counterintuitive, but for many thinkers, exploring whiteness is useful in determining the conventional parameters of Black identity. The act of identifying and challenging these boundaries creates the opportunity for imagining a unity not plagued by restrictive conceptions of blackness. Therefore, turning inward does not appear as a mere rejection of whiteness in favor of shoring up blackness. The chapter then highlights how the rhetoric of White innocence provides the foundati

Résumé :

Any attempt to reverse the condition of African Americans in New England had to consider what a small fraction of the overall population they were. Success depended upon unity of African Americans and changing attitudes and behaviors of white New Englanders. This chapter analyzes those efforts from what to call themselves to creating black institutions to enlisting white support. Activists in the 1830s largely focused on the tactic of uplift, primarily meaning education and self-improvement societies. The idea was that African Americans needed to improve themselves to reduce white prejudice as

The nineteenth-century cultural elevation of science puts it in some respects in an analogous position to that previously occupied by religion in marking out Western civilization. Beginning in the nineteenth century in Germany, France, and Britain, there developed a comprehensive cultural investment in the idea of the unity of science, which played a crucial role in taking over this task from religion. In this chapter the political, social, and ideological motivations behind the nineteenth-century advocacy of the unity of science are explored. At the same time, it examines the formative moves

Since Tw/Tb in gas-turbine cooling passages can be as high as 2.2 and vary appreciably along the passage, this study examines if it is necessary to match the rate of change in Tw/Tb when measuring Nu, whether Nu measured at Tw/Tb near unity needs to be scaled before used in design and analysis of turbine cooling, and could
