Some Remarks on Strichartz Estimates for Homogeneous Wave Equation

Abstract

We give several remarks on Strichartz estimates for homogeneous wave equation with special attention to the cases of $L_x^{\infty }$ estimates, radial solutions and initial data from the inhomogeneous Sobolev spaces. In particular, we give the failure of the endpoint estimate $L_t^4{L}_x^{\infty }$ for $n=2$.
