[1008.1127] Closed timelike curves and causality violation

I liked this review of closed timelike curves (CTCs) and time travel in general relativity. The presentation is easy to follows, but has sufficient technical details to appreciate what is really going on. Especially interesting was the analysis showing how generic CTCs are in rotating axisymmetric solutions, and the examples of spacetimes with CTCs without exotic matter.
