Strong Logarithmic Sobolev Inequalities for Log-Subharmonic Functions

Abstract : We prove an intrinsic equivalence between strong hypercontractivity and a strong logarithmic Sobolev inequality for the cone of logarithmically subharmonic (LSH) functions. We introduce a new large class of measures, Euclidean regular and exponential type, in addition to all compactly-supported measures, for which this equivalence holds. We prove a Sobolev density theorem through LSH functions, and use it to prove the equivalence of strong hypercontractivity and strong logarithmic Sobolev inequality for such log-subharmonic functions.
