Resumen
Using a Newtonian approximation we developed a quantitative criterion for the collapse of a spherical distribution of matter under an isolated texture field. In particular, we found the evolution of an overdense region is strongly determined by two parameters: the energy scale of symmetry breaking (eta) and the initial radius of the system. Applying our collapse criterion to typical galaxy scales we verified the formation of 10(11)-M. objects at z less than or similar to 9 and 10(12)-M. objects at z less than or similar to 5. 309 4 817 822
