| Abstract: | Gauss-Bonnet gravity has superluminal modes because of non-canonical kinetic terms for gravitons. Superluminal modes make the causal structure non-trivial. In my talk, after the brief review of the technique to analyze the causal structure, called characteristics, the causal structure in Gauss-Bonnet gravity will be discussed. |
