Advantages, novelties and surprises in 2+1 dimensional gravity

Alejandra Castro, University of Amsterdam

Three dimensional gravity has the potential to be an exactly solvable model of quantum gravity. It has also shown to provide novel insight to the fundamental mechanics behind holography. I will overview recent progress on non-perturbative aspects of these theories with emphasis on black holes. In particular, I will review the relation between Chern-Simons theory and 3D gravity, which provides an interesting arena to explore locality in quantum gravity--and the lack of it. Entanglement is an important clue to understanding holography; the last portion of the talk will focus on how to formulate entanglement entropy for these theories and some interesting applications of these new developments
