Atrator no sentido pullback e trajetórias completas extremas para problemas governados pelo p-Laplaciano
(Universidade Federal de São Carlos, 2011-03-25)
We study non-autonomous problems with the main part given by the p- Laplacian and establish existence results of pullback attractor, comparison of solutions and existence of a maximal and a minimal complete trajectories. ...
Resolubilidade local para duas classes de campos de vetores suaves complexos
(Universidade Federal de São Carlos, 2016-07-28)
This work study complex linear partial differential operators of order one without
having terms of zero order (complex vector fields). We have established a necessary and
suficient condition for local solvability of a ...
Classificação de ações de Z2k fixando espaços projetivos relativos a anéis diferentes
(Universidade Federal de São Carlos, 2013-12-13)
Let M be a closed smooth manifold and T : M ! M be an C1 involution defined on M. It is known that if F is the set of fixed points of T, then it is a finite union of closed submanifolds of M. Given F, a problem in this ...
O problema pseudoviscoso e a equação de BBM-Burgers estocásticos
(Universidade Federal de São Carlos, 2016-09-30)
This work is divided in two parts: In the first part, we study the convergence of a sequence
of approximating solutions to a solution of the stochastic conservation law, in the additive and
multiplicative case. In the ...
Aplicações entre 3-variedades Sol e números de Nielsen para coincidências
(Universidade Federal de São Carlos, 2017-08-24)
Let MA be the torus bundle over S1 obtained using as gluing map an Anosov matrix A. In this work we discuss maps from MA to MD and compute the coincidence Nielsen numbers for some families of such maps, moreover we use ...
Limites singulares para equações do tipo Rosenau-KdV-RLW e Benney-Lin : existência e convergência de soluções
(Universidade Federal de São Carlos, 2017-09-01)
We consider the approximations
@tu + @xf(u) + b1@3xu + b2@t@2xu + 2c@t@4 xu = @2xu (4)
and
@tu + @xf(u) + @2xu + 2b@3 xu + 3c@4xu + 5d@5xu = @2xu (5)
of the Rosenau-KdV-RLW and Benney-Lin equations and ...
Ações de Zr2 fixando RPj U CPk
(Universidade Federal de São Carlos, 2017-03-07)
The classification up to equivariant cobordism of smooth involutios (M, T) having fixed set F is a classical problem in cobordism theory. This classification has been studied for several cases of F, of which we highlight ...
Euclidean hypersurfaces with genuine conformal deformations in codimension two
(Universidade Federal de São Carlos, 2018-01-05)
We classify hypersurfaces f:Mn → Rn+1 with a principal curvature of multiplicity n − 2 that admit a genuine conformal deformation f':Mn → Rn+2. That a conformal deformation f':Mn → Rn+2 of f is genuine means that there ...
Identidades e polinômios centrais com involução para a álgebra das matrizes triangulares superiores 2x2
(Universidade Federal de São Carlos, 2018-08-16)
Let F be a field of characteristic diferent from 2. Denote by UT2(F) the 2x2 upper triangular matrix F-algebra. If * is a involution of first kind of UT2(F), denote by Id(UT2(F); * and
C(UT2(F); *) the set of its ...
Invariantes de germes de aplicações
(Universidade Federal de São Carlos, 2017-04-19)
In this work, we show relations between invariants of map germs. First, we consider an analytic function germ f : (X, 0) —(C, 0) on an isolated determinantal singularity and we present a relation between the Euler obstruction ...
