Abstract

We investigate the possibility of improving the pp-Poincar\'e inequality HNupΛpup\|\nabla_{\mathbb{H}^N} u\|_p \ge \Lambda_p \|u\|_p on the hyperbolic space, where p>2p>2 and Λp:=[(N1)/p]p\Lambda_p:=[(N-1)/p]^{p} is the best constant for which such inequality holds. We prove several different, and independent, improved inequalities, one of which is a Poincar\'e-Hardy inequality, namely an improvement of the best pp-Poincar\'e inequality in terms of the Hardy weight rpr^{-p}, rr being geodesic distance from a given pole. Certain Hardy-Maz'ya-type inequalities in the Euclidean half-space are also obtained.
