Title: Gauss Bonnet Gravity and Singularity Crossing

Abstract: 

We study the effect of adding a Gauss Bonnet term to general relativity, in five dimensions, on modifying the singular behavior of certain gravitational solutions. These solutions are the Gauss Bonnet FRW cosmology and spherically symmetric Black hole solution. In these cases, we were able to show that nonspacelike geodesics can be extended across the singularities, which render these spacetimes geodesically complete. We check the consistency of these extensions with the field equations against the known Gauss Bonnet junction conditions.
