Sharp Strichartz estimates in spherical coordinates
arXiv:1612.02594 · doi:10.3934/cpaa.2017100
Abstract
We prove almost Strichartz estimates found after adding regularity in the spherical coordinates for Schrödinger-like equations. The estimates are sharp up to endpoints. The proof relies on estimates involving spherical averages. Sharpness is discussed making use of a modified Knapp-type example.
