Lovelock inflation and the number of large dimensions
arXiv:0707.0499 · doi:10.1088/1126-6708/2007/11/003
Abstract
We discuss an inflationary scenario based on Lovelock terms. These higher order curvature terms can lead to inflation when there are more than three spatial dimensions. Inflation will end if the extra dimensions are stabilised, so that at most three dimensions are free to expand. This relates graceful exit to the number of large dimensions.
