Abstract

In this paper, we study a type of one-field approach for open inflationary universe scenario in the context of braneworld models with a Gauss-Bonnet correction term. For a one-bubble universe model, we determine and characterize the existence of the Coleman-De Lucia instanton together with the period of inflation after tunneling has occurred. Our results are compared with those analogous obtained when the usual Einstein Theory of Gravitation is used. © 2008 World Scientific Publishing Company.
