Abstract

We consider a (4+N)-dimensional Einstein gravity coupled to a nonlinear sigma model. This theory admits a solution in which the N extra dimensions contract exponentially while the ordinary space expand exponentially. Physically, the nonlinear sigma fields induce the dynamical compactification of the extra dimensions, which in turn drives inflation. No inflatons are required.
