Resumen de Localizing groups with action
When localizing the semidirect product of two groups, the effect on the factors is made explicit. As an application in Topology, we show that the loop space of a based connected CW-complex is a P-local group, up to homotopy, if and only if p1X and the free homotopy groups [Sk-1, OX], k = 2, are P-local.
