Sharp trace inequalities for fractional Laplacians

Einav, Amit; Loss, Michael

Michael Loss



Abstract

The sharp trace inequality of José Escobar is extended to traces for the fractional Laplacian on Rn, and a complete characterization of cases of equality is discussed. The proof proceeds via Fourier transform and uses Lieb’s sharp form of the Hardy-Littlewood-Sobolev inequality.
