Abstract
Volterra integro-differential equations with unbounded operator coefficients in a Hilbert space are studied. The equations under consideration are abstract hyperbolic equations perturbed by terms containing Volterra integral operators. These equations can be realized as integro-differential partial differential equations arising in the theory of viscoelasticity (see [4, 6]) and as the Gurtin–Pipkin integro-differential equations (see [1, 6]), which describe the process of heat propagation in media with memory at finite rate; these equations arise also in problems of averaging in multiphase media (Darcy’s law) (see [9]).
