This study presents a simplified approach to studying the dynamics of globaltexture collapse. We derive equations of motion for a spherically symmetricfield configuration using a two parameter ansatz. Then we analyse the effectivepotential for the resulting theory to understand possible trajectories of thefield configuration in the parameter space of the ansatz. Numerical results aregiven for critical winding and collapse time in spatially flat non-expanding,and flat expanding universes. In addition, the open non-expanding andopen-expanding cases are studied.Comment: 12 pages, figures available from author, BROWN-HET-895, uses phyzz
