Abstract
We prove that if a super-Poincaré inequality is satisfied by an infinitesimal generator \(-A\) of a symmetric contraction semigroup on \(L^2\) and that is contracting on \(L^1\), then it implies a corresponding super-Poincaré inequality for \(-g(A)\) for any Bernstein function \(g\). We also study the converse of this statement. We prove similar results for Nash-type inequalities. We apply our results to Euclidean, Riemannian, hypoelliptic and Ornstein–Uhlenbeck settings.
