Sharp k-order Sobolev inequalities in the hyperbolic space
arXiv:0708.0269
Abstract
In this paper, we obtain the sharp -th order Sobolev inequalities in the hyperbolic space ${\H}^n$ for all . This gives an answer to an open question raised by Aubin in [5, p.176-177] for $W^{k,2}({\H}^n)$ with . In addition, we prove that the associated Sobolev constants are optimal.
