  The aim of this paper is to present a linear viscoelastic model based on
Prabhakar fractional operators. In particular, we propose a modification of the
classical fractional Maxwell model, in which we replace the Caputo derivative
with the Prabhakar one. Furthermore, we also discuss how to recover a formal
equivalence between the new model and the known classical models of linear
viscoelasticity by means of a suitable choice of the parameters in the
Prabhakar derivative. Moreover, we also underline an interesting connection
between the theory of Prabhakar fractional integrals and the recently
introduced Caputo-Fabrizio differential operator.
