Abstract
In this paper we show that certain types of cosmological brane configurations may induce topological inflation. In generic models for topological inflation, there is a strict bound for the potential of the inflaton field. Naively, it seems that these constraints can be removed if inflation starts with a hybrid potential. However, it is difficult to combine topological inflation and hybrid inflation, because of the difference in their initial conditions. In this paper, we show some examples in which a novel type of topological inflation is realized with the unconventional hybrid potential.
