NUMERICAL TWISTER PROCEDURE FOR SOLVING A NONLINEAR FIELD EQUATION

This paper concentrates on an integrable SU(2) chiral equation in two space and one time dimensions, admitting soliton solutions. It is, in effect, a reduction of the self-dual Yang-Mills equations in 2+2 dimen sions, and can therefore be solved by twister methods. However, only s ome solutions can be constructed explicitly, and to solve a general in itial-value problem requires some kind of numerical computation. The p aper describes a way of implementing the twister solution procedure nu merically in order to do this. (C) 1994 American Institute of Physics.
