## Abstract Let __u__ and __v__ be, respectively, the solutions to the Cauchy problems for the dissipative wave equation $$u\_{tt}+u\_tโ\Delta u=0$$\nopagenumbers\end and the heat equation $$v\_tโ\Delta v=0$$\nopagenumbers\end We show that, as $t\rightarrow+\infty$\nopagenumbers\end, the norms
Consider the initial boundary value problem for the linear dissipative wave equation ( + โ t )u = 0 in an exterior domain โฆ โ R N . Using the so-called cut-off method together with local energy decay and L 2 decays in the whole space, we study decay estimates of the solutions. In particular, when N
