Abstract:In this talk, we will first discuss the quantitative stability for the Hardy-Littlewood-Sobolev (HLS) inequalities. By establishing the relation between the stability of HLS inequalities and the stability of fractional Sobolev inequalities, we also give the quantitative stability of the fractional Sobolev inequalities. Finally, we also discuss the optimal asymptotic lower bound for fractional Sobolev inequality and Log Sobolev inequality on the sphere. Our proofs are based on the competing symmetries, the continuous Steiner symmetrization inequality for the HLS integral, complicated orthogonal estimate, and the dual stability theory. This talk is based on the joint work with Prof. Lu from Connecticut University and Prof. Tang from Beijing Normal University.
