Geometric averaging operators and nonconcentration inequalities

Philip T. Gressman

Vol. 15 (2022), No. 1, 85–122
Abstract

This paper is devoted to a systematic study of certain geometric integral inequalities which arise in continuum combinatorial approaches to Lp-improving inequalities for Radon-like transforms over polynomial submanifolds of intermediate dimension. The desired inequalities relate to and extend a number of important results in geometric measure theory.
