Boundedness of Bilinear Bessel Potentials

Functional Analysis 2026-03-18 v1

Abstract

In analogy with bilinear Riesz potentials, we introduce bilinear Bessel potentials and characterize their boundedness from Lp×LqL^p\times L^q into Lebesgue and Lorentz spaces Lr,α.L^{r,\alpha}. In several cases we identify the optimal Lorentz indices by constructing explicit counterexamples.
