Manifolds with 2-nonnegative Ricci operator
(Pacific Journal MathematicsBerkeleyEUA, 2002)
Classes características de variedades topológicas e generalizadas
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Matemática - PPGMCâmpus São Carlos, 2022-03-24)
In this work, we will initially present generalized bundles, a concept developed by Fadell with
the objective of generalizing vector bundles, Stiefel-Whitney classes andWu’s formula from the
context of smooth manifolds ...
Equigeodesics on Generalized Flag Manifolds with Two Isotropy Summands
(Birkhauser Verlag AgBaselSuíça, 2011)
Functions and vector fields on C(ℂPn)-singular manifolds
(2015-12-01)
In this paper we study functions and vector fields with isolated singularities on a C(ℂPn)-singular manifold. In general, a C(ℂPn)-singular manifold is obtained from a smooth (2n + 1)-manifold with boundary which is a ...
Global behavior of the Ricci flow on generalized flag manifolds with two isotropy summands
(Elsevier Science BvAmsterdamHolanda, 2012)
EQUIVARIANT PATH FIELDS ON TOPOLOGICAL MANIFOLDS
(JULIUSZ SCHAUDER CTR NONLINEAR STUDIES, 2009)
A classical theorem of H. Hopf asserts that a closed connected smooth manifold admits a nowhere vanishing vector field if and only if its Euler characteristic is zero. R. Brown generalized Hopf`s result to topological ...
FUNCTIONS AND VECTOR FIELDS ON C(CPn)-SINGULAR MANIFOLDS
(Juliusz Schauder Ctr Nonlinear Studies, 2015-12-01)
In this paper we study functions and vector fields with isolated singularities on a C(CPn)-singular manifold. In general, a C(CPn)-singular manifold is obtained from a smooth (2n+1) -manifold with boundary which is a ...
Generalized complex and paracomplex structures on product manifolds
(Real Acad Ciencias Exactas Fisicas & Naturales, 2020-07-13)
On a product manifold (M, r), we consider four geometric structures compatible with r, e.g. hyper-paracomplex or bi-Lagrangian, and define distinguished generalized complex or paracomplex structures on M, which interpolate ...
