Some Remarks on Strichartz Estimates for Homogeneous Wave Equation
Daoyuan Fang, Chengbo Wang
Abstract
We give several remarks on Strichartz estimates for homogeneous wave equation with special attention to the cases of L∞x estimates, radial solutions and initial data from the inhomogeneous Sobolev spaces. In particular, we give the failure of the endpoint estimate L4t L∞x for n=2.
