The complete expressions corresponding to space and time derivatives of Volterra's integral representation of the time-dependent scalar wave equation are presented in this paper. The concept of finite part of an integral is used in order to compute boundary kernels contributions. Time integration of
The numerical simulation of nonlinear gravity waves propagating at the surface of a perfect fluid is now usually solved by totally For this kind of equations in unbounded domains, exact nonlinear time-domain numerical models in two dimensions, and absorbing boundary conditions nonlocal in both space
## Abstract Timeβdomain integral equation analyses are prone to instabilities, in a range of applications areas including acoustics, electrodynamics and elastodynamics, and a variety of retrospective averaging schemes have been proposed to improve matters. In this paper, we investigate stability be
