Reduction principle for Gaussian K-inequality

Abstrakt

We study interpolation properties of operators (not necessarily linear) which satisfy a specific K-inequality corresponding to endpoints defined in terms of Orlicz-Karamata spaces modeled upon the example of the Gaussian-Sobolev embedding. We prove a reduction principle for a fairly wide class of such operators. (c) 2022 Elsevier Inc.
