Existence of Complementary and Variational Weak Solutions to Obstacle Problems for a Quasilinear Wave Equation
João Paulo Dias, Wladimir Neves, José Francisco Rodrigues
We prove the existence of weak solutions for the one obstacle problem associated with a class of quasilinear wave equations in one space dimension, extending previous results obtai…
On short wave-long wave interactions\\ in the relativistic context: Application to the Relativistic Euler Equations
João Paulo Dias, Hermano Frid
In this paper we introduce a model of relativistic short wave-long wave interaction where the short waves are described by the massless -dimensional Thirring model of nonlinea…
