Computation of the spatial derivatives with non-local differential operators, such as the Fourier pseudospectral method, may cause strong numerical artifacts in the form of noncausal ringing. This situation occurs when regular grids are used. The problem is attacked by using a staggered pseudospectr

A staggered Runge-Kutta (staggered RK) scheme is a Runge-Kutta type scheme using a time staggered grid, as proposed by Ghrist et al. in 2000 [6]. Afterwards, Verwer in two papers investigated the efficiency of a scheme proposed by Ghrist et al. [6] for linear wave equations. We study stability and c
## IN MEMORY OF NORMAN LEVINSON The LB norm in space-time of a solution of the Klein-Gordon equation in two space-time dimensions is bounded relative to the Lorentz-invariant Hilbert space norm; the L, norms for p > 6 are bounded relative to certain similar larger Hilbert space norms, including th
