Abstract

Let p(t; x) be the fundamental solution to the problem (Formula Presented), then the kernel p(t; x) becomes the transition density of a Lévy process delayed by an inverse subordinator. In this paper we provide the asymptotic behaviors and sharp upper bounds of p(t; x) and its space and time fractional derivatives (Formula Presented); where Dn x is a partial derivative of order n with respect to x, (-Δx)γ is a fractional Laplace operator and Dσ t and Iσ t are Riemann-Liouville fractional derivative and integral respectively.
