Abstract:

We study the multiscale homogenization of a nonlinear hyperbolic equation in a periodic setting. We obtain an accurate omogenization result. We also show that as the nonlinear term depends on the microscopic time variable, the global homogenized problem thus obtained is a system consisting of two hyperbolic equations. It is also shown that in spite of the presence of several time scales, the global homogenized problem is not a reiterated one.

Key words: hyperbolic, multiscale, nonlinear
