Abstract
The equations of linear viscoelasticity with a bounded memory kernel have been shown to propagate singularities in a similar way as hyperbolic equations. In this paper, we investigate a model problem for a certain class of unbounded memory kernels. It is shown thatC ∞-solutions are obtained, although there is a discontinuity in the boundary conditions.
