EXTENSIONS OF 2D GRAVITY
Copyright policy )EXTENSIONS OF 2D GRAVITY
After reviewing some aspects of gravity in two dimensions, I show that non-trivial embeddings of sl(2) in a semi-simple (super) Lie algebra give rise to a very large class of extensions of 2D gravity. The induced action is constructed as a gauged WZW model and an exact expression for the effective action is given.
