abstract = {<p style="text-align: justify;">An $hp$-version of $C^0$-CPG time-stepping method for second-order Volterra
integro-differential equations with weakly singular kernels is studied. In contrast to
the methods reducing second-order problems to first-order systems, here the CG and
DG methodologies are combined to directly discretise the second-order derivative. An
a priori error estimate in the $H^1$-norm, fully explicit with respect to the local discretisation and regularity parameters, is derived. It is shown that for analytic solutions with
start-up singularities, exponential rates of convergence can be achieved by using geometrically refined time steps and linearly increasing approximation orders. Theoretical
results are illustrated by numerical examples.</p>},
