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

      Santiago, Eric Busatto (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Matemática - PPGM, Câmpus São Carlos, 22/12/2020)
      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 

      Gobbi, Ray Santos (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Matemática - PPGM, Câmpus São Carlos, 24/04/2024)
      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) ,& ...
