报告摘要：In this talk, we will first recall some sharp geometric inequalities and their extremals. Then we will present our recent progress on the existence of extremals for Hardy-Sobolev-Maz’ya inequalities (HSM) on the upper-half space. We develop the dual theory of minimizing sequence, the concentration-compactness principle for radial function on the hyperbolic setting, which combined with Helgason-Fourier analysis and the Riesz rearrangement inequality on the hyperbolic space, resolves the lack of compactness. As an application, we also obtain the existence and symmetry of the positive solution for the high order critical Brezis-Nirenberg equation on the entire hyperbolic space.
