Os teoremas de índice de Poincaré
(Universidade Estadual Paulista (UNESP), 2014)
Profinite completions of orientable Poincare duality groups of dimension four and Euler characteristic zero
(European Mathematical SocZurichSuíça, 2009)
Quantifying physical and structural soil properties using X-ray microtomography
(2018-05-15)
One of the current challenges in the study of recovering soil architecture is physically evaluating the internal soil structure in unconventional ways. The elaboration of consistent methods and physical parameters has ...
Os teoremas de índice de Poincaré
(Universidade Estadual Paulista (Unesp), 2011-03-01)
O objetivo deste trabalho é apresentar uma demonstração combinatória dos teore- mas de Índice de Poincaré, a saber: Sejam D um disco e γ seu bordo. Seja V um campo vetorial contínuo sobre D com pontos críticos isolados P1, ...
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 ...
Multiple solutions for periodic perturbations of a delayed autonomous system near an equilibrium
(American Institute of Mathematical Sciences, 2019)
Small non-autonomous perturbations around an equilibrium of a nonlinear delayed system are studied. Under appropriate assumptions, it is shown that the number of T-periodic solutions lying inside a bounded domain Ω ⊂ R N ...
Minimal Morse flows on compact manifolds
(Elsevier Science BvAmsterdamHolanda, 2006)
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 ...
