Local coercivity for semilinear elliptic problems 

Mendoza Aranda, José Miguel (Universidade Federal de São Carlos, 2018-03-13)
We study a non-homogeneous semilinear eliptic problem with Dirichlet condition baundary in a bounded domain and we show existence of solution. Also extend the result to the fraccionary laplacian case and to the homogeneous ...

Non-autonomous Klein-Gordon-Zakharov system: pullback dynamics in the continuous and impulsive approaches 

Santiago, Eric Busatto (Universidade Federal de São Carlos, 2020-12-22)
This work is dedicated to study a non-autonomous formulation of the Klein-Gordon-Zakharov system, which is a coupled system consisting of two non-autonomous evolution equations, where each one is of second order in time. ...

Analiticidade, na variável espacial, da solução do problema de Caucky para a equação de KdV 

Miotto, Márcio Luís (Universidade Federal de São Carlos, 2006-03-13)
In this work we use bilinear estimates and point fix theorem to show that the solution to the initial value problem for the Korteweg-de Vries equation with analytic periodic initial data is analytic and periodic in the ...

Uma nova caracterização dos Espaços de Sobolev W^{1,p}(R^n) 

Elias, Thaysa Fernanda (Universidade Federal de São Carlos, 2018-04-06)
In this work we will present a new characterization of the Sobolev space W^{1,1}(\R^n) and also we give another proof of the characterization of the Sobolev space W^{1,p}(\R^n), 1<p<\infty, in terms of Poincaré inequalities. ...

Espectro do Laplaciano de Dirichlet-Neumann em faixas estreitas 

Bello, Diana Carolina Suarez (Universidade Federal de São Carlos, 2020-08-11)
Let $\Omega_\varepsilon$ be a thin strip in $\mathbb{R}^2$ and $-\Delta_{DN}^{\Omega_\varepsilon}$ the Dirichlet-Neumann Laplacian in $\Omega_\varepsilon$. In this work, we study the spectral problem of $-\Delta_{DN}^{\O ...

Classificação de centros Hamiltonianos polinomiais biquadrados, e isocronicidade trivial versus formas canônicas para aplicações polinomiais no plano de Jacobiano unitário 

Appis, Raul Felipe (Universidade Federal de São Carlos, 2022-10-10)
This work, we classify a non- degenerate center at the origin of a planar Hamiltonian system associated to a function of the form $H(x,y)=A(x)+B(x)y^2 + C(x)y^4$, where $A$, $B$ and $C$ are polynomials. After seing a ...

Grafeno multicamadas através de grafos quânticos periódicos: cones de Dirac 

Rocha, Vinícius Lourenço da (Universidade Federal de São Carlos, 2020-03-06)
We study the spectral characterization and Dirac cones, always through periodic quantum graphs, in three situations. Firstly, we model bidimensional honeycomb materials, for instance, Graphene and Boron Nitride. We consider ...

Localização dinâmica para perturbações de operadores de Schrödinger discretos com campo elétrico 

Pigossi, Mariane (Universidade Federal de São Carlos, 2018-02-02)
We study the spectrum and the dynamical localization of some discrete quantum systems with uniform electric fields under suitable perturbations with exponential decay in the matrix elements. We consider three particular ...

Espectro absolutamente contínuo do operador Laplaciano 

Mamani, Carlos Ronal Mamani (Universidade Federal de São Carlos, 2018-04-06)
Let $\Omega$ be a periodic waveguide in $\mathbb R^3$, we denote by $-\Delta_\Omega^D$ and $-\Delta_\Omega^N$ the Dirichlet and Neumann Laplacian operators in $\Omega$, respectively. In this work we study the absolutely ...

Hipoelipticidade global de campos vetoriais no toro TN 

Nascimento, Moisés Aparecido do (Universidade Federal de São Carlos, 2010-06-21)
In this work, we will see that if the transpose operator of a smooth real vector field L defined on the N-dimensional torus, regarded as a linear differential operator with coefficients in C1(TN), is globally hypoelliptic, ...
