| contents | Self-similarity in a Kantowski-Sachs universe with a string cloud Héctor Martínez Carlos Peralta Física, Astronomía y Matemáticas Self similar strings universe inflation We study a cosmological model with very simple solutions characterized by string clouds. Assuming self-similar symmetry for a Kantowski-Sachs spacetime we study the gravitational effects of the cosmic strings. It is also assumed that the primitive universe enters in a falsevacuum-dominated era, accelerating the expansion in a time period of the order of 10¡35 sec (a phase transition), satisfying all the energyconditions. Finally, we examine the possibility that in the last stages of this evolution, the geometry of the universe could be flat. 2005 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57063704 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
