Abstract
We present a new time-symmetric evolution formula for the scalar wave equat ion. It is simply related to the classical D'Alembert or spherical means re presentations, but applies equally well in two space dimensions. It can be used to develop stable, robust numerical schemes on irregular meshes. (C) 2 000 Academic Press.
