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…

Variational and Quasi-variational solutions to thick flows
Jos\é Francisco Rodrigues, Lisa Santos
We formulate the flow of thick fluids as evolution variational and quasi-variational inequalities, with a variable threshold on the absolute value of the deformation rate tensor. I…
