Strings, Textures, Inflation and Spectrum Bending

Abstract

We discuss relationship between inflation and various models of production of density inhomogeneities due to strings, global monopoles, textures and other topological and non-topological defects. Neither of these models leads to a consistent cosmological theory without the help of inflation. However, each of these models can be incorporated into inflationary cosmology. We propose a model of inflationary phase transitions, which, in addition to topological and non-topological defects, may provide adiabatic density perturbations with a sharp maximum between the galaxy scale $l_g$ and the horizon scale $l_H$.
