摘要
We study the numerical solutions of the initial boundary value problems for the Volterra-type evolutionary integal equations, in which the integral operator is a convolution product of a completely monotonic kernel and a positive definite operator, such as an elliptic partial-differential operator. The equation is discretized in time by the Runge-Kutta convolution quadrature. Error estimates are derived and numerical experiments reported. (c) 2014 Wiley Periodicals, Inc.
