BOZZETTI, CRISTINA. "Absolute parallelisms on almost complex manifolds." Doctoral thesis, Università degli Studi di Milano-Bicocca, 2015. http://hdl.handle.net/10281/88468.
Full textIn almost complex manifolds (M⁴,J) of real dimension 4 it is interesting to study when it is possible to construct an absolute parallelism, namely when (M⁴,J) admits an {e}-structure. Although in general this is not true, on almost complex manifolds in which the image of the Nijenhuis forms a bundle, called fiber bundle, which is not integrable, there exists a double absolute parallelism. As a consequence, it results that the group of the automorphisms Aut(M⁴,J) of (M⁴,J) is a Lie group of dimension less or equal to 4, and its isotropy subgroup has at most two elements. Moreover it is possible to define a natural metric on (M⁴,J). When (M⁴,J) is locally homogeneous, the Lie algebra generated by the fields that determinate the double absolute parallelism allows us to classify these almost complex manifolds. In particular, the classification in the case when the Lie algebra is not solvable is introduced, while several examples are shown to explain how to make the classification when the algebra is solvable.

Gérard, Maxime. "Méthodes de sélection de structures presque complexes dans le cadre symplectique." Thesis, Université de Lorraine, 2018. http://www.theses.fr/2018LORR0051/document.
Full textGiven a symplectic manifold $(M,\omega)$, there always exist almost complex $\omega,$-compatible positive structures. The problem studied in this thesis is to find methods to select some of these structures. Answers have already been suggested by V. Apostolov and T.Draghici, J. G. Evans, and J. Keller and M. Lejmi. We are mainly interested here in selection methods defined in terms of the Nijenhuis tensor. The problem of selecting geometric objects can be tackled in various ways. One of them is to decompose into irreducible components some tensors naturally associated with the structure, and to impose conditions on some of those components. We prove that the Nijenhuis tensor is irreducible under the action of the unitary group. This irreducibility does not allow to impose any linear condition on the Nijenhuis tensor, except the vanishing of it, which corresponds to Kähler manifolds. Another possible method of selection is to impose conditions on distributions related to the problem. We study distributions defined by the Nijenhuis tensor. Our results concern the possible dimensions and properties of involutivity of these distributions. We give examples which are invariant under the action of a group, on some symplectic groups and on twisted bundles over some Riemannian manifolds. The last method considered in this work consists in looking for extremals of functionals defined from the data. To construct the simplest functional defined in terms of the Nijenhuis tensor, we integrate a polynomial function of the second degree into the components of this tensor. All such polynomials are multiple of the square of the norm of this tensor. This functional is the one studied by Evans; the drawback for our selection problem is that there exist examples of compact symplectic manifolds which do not admit any K\"ahler structure but such that the infimum of the functional is zero

Full textEstudiamos 2-formas de Killing-Yano invariantes a izquierda sobre grupos de Lie, o equivalentemente, sobre álgebras de Lie. Más particularmente, clasificamos las álgebras de Lie de dimensión 4 que admitan tales estructuras, y para cada una de tales álgebras, listamos todas las posibles estructuras de Killing-Yano (salvo equivalencia). Realizando extensiones centrales de estas álgebras obtenemos ejemplos de 2-formas de Killing-Yano Conformes en dimensión 5. Las álgebras de Lie obtenidas resultan ser aquellas álgebras de Lie sasakianas (de dimensión 5) con centro no trivial. Analizamos tensores de Killing-Yano invariantes para variedades homogéneas G/K que admitan una métrica G-invariante. Más específicamente estudiamos la ecuación de Killing-Yano en variedades bandera generalizadas y damos ejemplos concretos en variedades bandera maximales de dimensiones 6, 8 y 12.
We study left invariant Killing-Yano 2-forms on Lie groups. This is equivalent to work at the Lie algebra level. In particular, we classify four dimensional Lie algebras that admit such structures, and for each of them we list all the possibles Killing-Yano structures (up to equivalence). Doing central extensions on the obtained Lie algebras, we find examples of Conformal Killing-Yano tensors in dimension five. Further, the obtained central extensions are Sasakian Lie algebras of dimension five with no trivial center. We analyse G-invariant Killing-Yano tensors on homogeneous spaces G/K that admits a G-invariant metric. As an application we study the Killing-Yano equation on Generalized flag manifolds and we find examples of invariant Killing Yano tensors on full flag manifolds of dimension six, eight and twelve.
