In this paper we present some results on the global existence of weak solutions to a nonlinear variational wave equation and some related problems. We first introduce the main tools, the Young measure theory and related compactness results, in the first section. Then we use the Young measure theory to prove the global existence of dissipative weak solutions to the asymptotic equation of the nonlinear wave equation, and comment on its relation to Camassa-Holm equations in the second...

Reiterated homogenization is studied for divergence structure parabolic problems of the form . It is shown that under standard assumptions on the function the sequence of solutions converges weakly in to the solution of the homogenized problem .

We study the homogenization of parabolic or hyperbolic equations like when the coefficients , (defined in ) take possibly high values on a -periodic set of grain-like inclusions of vanishing measure. Memory effects arise in the limit problem.
