Sparsity of Runge-Kutta convolution weights for the three-dimensional wave equation (Q486699)

The authors use an \(m\)-stage \(A\)-stable Runge-Kutta based convolution quadrature in order to approximate the time-domain single layer boundary operator. The main aim of the paper is to evaluate the kernels of the boundary integral operators which define the weights of the quadrature. These evaluations can significantly improve the computation of the convolution weights.
