Sistemas elípticos com pesos envolvendo o expoente crítico de Hardy-Sobolev
(Universidade Federal de São Carlos, 2007-11-20)
In this work, we will study the existence and nonexistence of positive weak solutions
for two classes of elliptic systems with weights. The first class will involve nonlinearities of
the type positone and semipositone. We ...
Confinamento de partículas quânticas a curvas do espaço
(Universidade Federal de São Carlos, 2010-05-24)
In this work we study dimensional reductions in some quantum systems; such reductions occur due to confinement of the particle from a tube in space to a curve. Our main goal is to find the effective hamiltonian operator ...
Micro-regularidade Gevrey de soluções de sistemas involutivos de edp's não lineares de primeira ordem
(Universidade Federal de São Carlos, 2010-03-05)
Let u be a C2 solution for a Gevrey involutive system of _rst order nonlinear partial di_erential equations. In this work, we show that the Gevrey wave front set of order s of u is contained in the characteristic set of ...
Injetividade de aplicações polinomiais via resolubilidade de campos vetoriais
(Universidade Federal de São Carlos, 2010-08-19)
Let F : Rn → Rn be a polynomial map such that the derivative map DF(x) be invertible for each x ∈ Rn. In this work, using techniques of solvability of suitable vector fields, we investigate the role of the ...
Existência global de soluções para alguns sistemas de leis de conservação
(Universidade Federal de São Carlos, 2010-08-17)
In this work, we studied the construction of weak solutions for some systems conservation laws and for a scalar conservation laws For the p-systems relativistic we use the Wave-front tracking based on Bressan, when the ...
Resolubilidade global para operadores diferenciais parciais reais de ordem um
(Universidade Federal de São Carlos, 2006-06-30)
The present work study the global solvability of first order real linear partial diferential
operators when the principal part has precisely one equilibrium point.
Moreover, examples and counterexamples are presented.
Preservação de mínimos locais de famílias de funcionais via gama-convergência e aplicações
(Universidade Federal de São Carlos, 2009-10-14)
Involuções fixando muitas componentes e melhorias para o 5/2-Teorema de J. Boardman
(Universidade Federal de São Carlos, 2012-03-05)
Let (Mm; T) be a smooth involution on a closed smooth m-dimensional manifold and F = n [j=0 Fj (n < m) its fixed point set, where Fj denotes the union of those components of F having dimension j. The famous Five Halves ...
O número de Milnor de uma singularidade isolada
(Universidade Federal de São Carlos, 2011-11-24)
Given (X; 0) C (CN; 0) a weighted homogeneous germ of hypersurface with isolated singularity and f : (CN; 0) - C a germ of function finitely determined with respect to X, we show that UBR(f;X) = U(f) + U(X; f), where U(f) ...
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. ...
