We consider the linear wave equation and the linear Schrodinger equation outside a compact, strictly convex obstacle in Rd with smooth boundary. In dimension d=3 we show that the linear wave flow and the linear Schrodinger flow satisfy the dispersive estimates as in R3. For d \geq 4, if the obstacle is a ball, we show that there exists points where the dispersive estimates fail for both wave and Schrodinger equations.
