Sistemas de inclusões diferenciais governadas pelo p-Laplaciano.
(Universidade Federal de São Carlos, 2004-03-01)
In this work we proof, by compactness methods, a local and global
existence result for p-laplacian diferential inclusions with p > 2. Most of relevant
theorems we need are in this text, including Monotone and Multivalued
Operators ...
A fórmula de aproximação de Baouendi -Treves
(Universidade Federal de São Carlos, 2009-03-06)
Let be a N-dimensional smooth manifold. Consider a locally integrable structure L of CT with fiber dimension 1 ≤ n < N and set m = N − n. We say that L is locally integrable if, for every p ∈ , there ...
O problema de Cauchy para a equação da onda cúbica
(Universidade Federal de São Carlos, 2011-05-27)
In this work, we study the result of global well-Posedness for the cubic wave equation @2 t u��_u+u3 = 0 in R_R3, where the Cauchy data is in the Sobolev space Hs(R3)_ Hs��1(R3) with 13 18 < s ...
Existência de padrões com difusibilidade variável e condição de fronteira de Neumann não linear
(Universidade Federal de São Carlos, 2009-03-24)
In this work we study a reaction-difusion problem with nonlinear Neumann boundary condition. The objective is to present suficient conditions on the diffusion coeficient so that the problem has an stable nonconstant ...
A influência da geometria do domínio sobre a existência de equilíbrios estáveis não-constantes para alguns sistemas parabólicos.
(Universidade Federal de São Carlos, 2004-04-23)
In this work we study the problem of existence of non-constant stable equilibria
to some parabolic systems. Specifically, the Ginzburg-Landau system, the
Landau-Lifshitz system and systems with skew-gradient structure. In ...
Hipoeliticidade global e vetores simultaneamente aproximáveis.
(Universidade Federal de São Carlos, 2003-08-11)
A necessary and sufficient condition is given for a sum of squares operator to be globally hypoelliptic. This condition is expressed in terms of Diophatine approximation properties of the coefficients. The proof of the ...
Sobre o modelo de supercondutividade de Ginzburg- Landau com efeito magnético em domínios delgados.

Extensões de distribuições quase-homogêneas
(Universidade Federal de São Carlos, 2007-02-02)
In this dissertation the author proves two results of extensions for IRn of distribution solutions in IRn{0} of the operator Lλ,a = n ∑ i=1 λixi@xi − a, with λ = (λ1, . . . , λn) E Rn ...
Continuidade de atratores para problemas parabólicos semilineares sob perturbações do domínio
(Universidade Federal de São Carlos, 2013-03-14)
In this work we will obtain the continuity of attractors for semilinear parabolic problems with Neumann boundary conditions relatively to perturbations of the domain. We will show that, if the perturbations on the domain ...
Leis de conservacão escalar: fórmula explícita e unicidade
(Universidade Federal de São Carlos, 2011-03-23)
We study scalar conservation laws, with the deduction of an explicit formula of a smooth solution with compact support, we also present the behavior of the solution given by the formula when the initial value is zero outside ...
