摘要:
We consider a kind of Yamabe problem whose scalar curvature vanishes in the unit ball B-n and on the boundary Sn-1 the mean curvature is prescribed. By combining critical points at infinity approach with Morse theory we obtain new existence results in higher dimensional case n >= 5, under suitable pinching conditions on the mean curvature function.
