 In this talk, we prove the diffusion phenomenon for
the linear wave equation with spacedependent
damping. Namely, we show that the asymptotic
profile of the solution is given by a solution of the
corresponding heat equation. The key point of the
proof is weighted energy estimates for higher order
derivatives.
