Scientific paper

Following work by Porter (1987), Regge calculus is used to simulate the dynamical collapse of model stars. The paper describes the general methodology of including a perfect fluid in dynamical Regge calculus space-times. The Regge-Einstein equations for spherical collapse are obtained and are then specialized to mimic a particular continuum gage. The equivalent continuum problem is also set up. This is to be solved using standard numerical techniques (i.e., the method of finite difference).
