Abstract
Two relativistic models for collapsing spheres at different stages of evolution, which include pre-relaxation processes, are presented. The influence of relaxation time on the outcome of evolution in both cases is exhibited and established. It is shown that relaxation processes c an drastically change the final state of the collapsing system. In par ticular, there are cases in which the value of the relaxation time det ermines the bounce or the collapse of the sphere.
