Abstract: We
consider wave propagation in the regime of random
geometric acoustics. We show, strarting from the
wave equation that in the long time - large distance
limit wave energy density behaves diffusively and
identify the diffusion coefficient in terms of the
statistics of the random medium. This is a joint
work with T. Komorowski.
