Homogenization of a nonlinear degenerate parabolic dierential equation

In this article, we study the homogenization of the nonlinear degenerate parabolic equation @tb( x " ;u") diva( x ; t " ;u ";ru") = f(x;t); with mixed boundary conditions(Neumann and Dirichlet) and obtain the limit equation as "! 0. We also prove corrector results to improve the weak convergence ofru" to strong convergence.
