Classes de Stiefel-Whitney e de Euler
(Universidade Estadual Paulista (Unesp), 2017-02-22)
Neste trabalho, apresentaremos uma descrição axiomática das classes de Stiefel-Whitney e, assumindo válidos estes axiomas, mostraremos algumas de suas aplicações. Posteriormente, definiremos as classes de Stiefel-Whitney ...

Fibrados, classes de Stiefel-Whitney e resultados de não imersãoFibrados, classes de Stiefel-Whitney e resultados de não imersão
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Matemática, 2012-09-24)
We present an introductory study of smooth manifolds, bundles and Stiefel- Whitney classes (of real vector bundles). We explained that, given a certain smooth m-dimensional manifold, the Stiefel- Whitney classes of its ...
On Whitney duals of operadic posets
(Medellín - Ciencias - Maestría en Ciencias - MatemáticasEscuela de matemáticasUniversidad Nacional de Colombia - Sede Medellín, 2020-04-27)
The notion of a Whitney dual for a graded partially ordered set (poset) $P$ with a minimum element $\hat{0}$ has been introduced recently by Gonz\'alez D'Le\'on and Hallam with some interesting connections to other areas ...

Explicit formulas for C1;1 Glaeser-Whitney extensions of 1-Taylor elds in Hilbert spaces
(Amer Mathematical Soc, 2018)
We give a simple alternative proof for the C-1,C-1-convex extension problem which has been introduced and studied by D. Azagra and C. Mudarra (2017). As an application, we obtain an easy constructive proof for the ...
Whitney equisingularity, euler obstruction and invariants of map germs from Cn to C3, n > 3
(2007-01-01)
We study how to minimize the number of invariants that is sufficient for the Whitney equisingularity of a one parameter deformation of any finitely determined holomorphic germ f : (Cn, 0) → (C3, 0), with n > 3. Gaffney ...
