Boa postura para alguns sistemas de equações dispersivas e para uma equação dispersiva
(Universidade Federal de São Carlos, 2020-10-30)
The main aim of this work is to establish the well posedness for a dispersive partial differential equations systems and for a partial differential equation, with initial data belonging to Gevrey space.
The proof ...
Existência de pullback atrator exponencial para uma família de problemas dominados por uma perturbação do p(x)-Laplaciano com difusão grande localizada, via método das l-trajetórias
(Universidade Federal de São Carlos, 2020-12-22)
In this work, we use the method of l-trajectories to prove the existence of a family of exponential attractors for autonomous nonlinear reaction-diffusion equations, involving the p(x)-Laplacian with large localized ...
Sobre uma família de equações de evolução não lineares : existência, classificação e instabilidade de soluções ondas viajantes
(Universidade Federal de São Carlos, 2018-03-26)
This thesis is concerned with the orbital instability for a specific class of periodic traveling wave solutions with the mean zero related to the modified Camassa-Holm equation. These solutions, called snoidal waves, are ...
Non-autonomous Klein-Gordon-Zakharov system: pullback dynamics in the continuous and impulsive approaches
(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. ...
Equações elípticas com o Laplaciano fracionário e não linearidades indefinidas
(Universidade Federal de São Carlos, 2024-04-24)
In this work, we investigate the existence, non-existence and multiplicity of positive solutions of the problem below,
\begin{equation*}
\left\lbrace \begin{array}{rll}
(-\Delta)^s u -\lambda u & = f(x)g(u) ,& ...
Comportamento assintótico para equações de placa fracionárias
(Universidade Federal de São Carlos, 2024-07-16)
In this work, we consider two second-order fractional semilinear plate equations in time. In the first problem, we investigate an equation governed by a biharmonic operator, with clamped boundary conditions in a smooth ...
Lebesgue solvability of equations associated to elliptic and canceling linear differential operators with measure data
(Universidade Federal de São Carlos, 2024-04-10)
In this thesis, we present new results on the solvability of the equation A*(x,D) f = µ for f in L^p, with complex measure data µ, associated to an elliptic linear differential operator A(x,D) of order m with variable ...
