Abstract

The endpoint Strichartz estimate ‖eitΔf‖Lt2Lx∞≲‖f‖L2 is known to be false in two space dimensions. Taking averages spherically on the polar coordinates x= ρω, ρ> 0 , ω∈ S¹, Tao showed a substitute of the form ‖eitΔf‖Lt2Lρ∞Lω2≲‖f‖L2. Here we address a weighted version of such spherically averaged estimates. As an application, the existence of solutions for the inhomogeneous nonlinear Schrödinger equation is shown for L² data.
