It is known that in many cases distributions of exponential integrals of Lévy processes are infinitely divisible and in some cases they are also selfdecomposable. In this paper, we give some ...

We consider, in an abstract setting, an instance of the Coleman-Gurtin model for heat conduction with memory, that is, the Volterra integro-differential equation ${\partial _t}u(t) - \beta \Delta u(t) ...
