Sharp heat kernel estimates in the Fourier-Bessel setting for a continuous range of the type parameter

Classical Analysis and ODEs 2014-02-12 v2

Abstract

The heat kernel in the setting of classical Fourier-Bessel expansions is defined by an oscillatory series which cannot be computed explicitly. We prove qualitatively sharp estimates of this kernel. Our method relies on establishing a connection with a situation of expansions based on Jacobi polynomials and then transferring known sharp bounds for the related Jacobi heat kernel.
