چکیده
In the context of supersymmetric models, we analyze the production of topological defects at the end of inflation driven by a conjugate pair of inflaton fields which are non-singlets under the continuous symmetry group of the theory. We find that magnetic monopoles of mass on the order of 10 13 GeV can survive inflation and be present in our galaxy at an observable level. We also consider cosmic strings as well as domain walls.

We propose a topological inflation model in the framework of supergravity with R invariance. This topological inflation model is not only free from the initial value problem of the inflaton field but also gives low reheating temperature which is favored in supergravity since the overproduction of graviti-nos is avoided. Furthermore, the predicted spectrum of the density fluctuations is generall...
