On Self – Similar Global Textures in an expanding Universe

  title={On Self – Similar Global Textures in an expanding Universe},
  author={Stefan {\AA}minneborg and Lars Bergstr{\"o}m},
We discuss self-similar solutions to O(4) textures in Minkowski space and in flat Friedmann-Robertson-Walker backgrounds. We show that in the Minkowski case there exist no solutions with winding number greater than unity. However, we find besides the known solution with unit winding number also previously unknown solutions corresponding to winding number less than one. The applicability of the non-linear sigma model approximation is discussed. We point out that no spherically symmetric exactly… CONTINUE READING
