Homogenization of obstacle problems in Orlicz-Sobolev spaces

Por Rafayel Teymurazyan (CMUC, Universidade de Coimbra).

Abstract: We prove homogenization results for obstacle problems in Orlicz-Sobolev spaces driven by p(.)-Laplace operator, as well as establish convergence of the coincidence sets.

Nonlinear Dirichlet Problems: Old and New

Por Lucio Boccardo (Dipartimento di Matematica, "Sapienza" Università di Roma).

Abstract: We present a review on the Stampacchia-Calderon-Zygmund theory for linear elliptic operators of second order with discontinuous coefficients and the corresponding theory for nonlinear operators of Leray-Lions type with nonregular data.

We shall also discuss classical and recent results, including work in progress, on the continuous dependence of the solutions with respect to right hand sides.
