This quantity comprises contributions through major staff within the box given on the workshop on Numerical Relativity held in Southampton in December 1991. Numerical Relativity, or the numerical resolution of astrophysical difficulties utilizing strong desktops to resolve Einstein's equations, has grown speedily over the past 15 years. it's now an incredible path to figuring out the constitution of the Universe, and is the one direction at present to be had for impending sure very important astrophysical situations. The Southampton assembly used to be striking for the 1st complete document of the recent 2+2 technique and the comparable null or attribute techniques, in addition to for updates at the tested 3+1 technique, together with either Newtonian and completely relativistic codes. The contributions variety from theoretical (formalisms, life theorems) to the computational (moving grids, multiquadrics and spectral methods).
