Summary: We formulate two-dimensional topological gravity starting from local \(N=2\) superconformal geometry. The theory is free from the very beginning. The usual ``twisting'' of the \(N=2\) algebra emerges from symmetry breaking when we expand about a nonzero value for one of the ghost fields.

Abstract There are two directions one might take to generalize supersymmetry and its models as we have presented them until this point: (a) to try to incorporate gravity as the fourth fundamental interaction, or (b) by using our experience with gauge theories, to try to make supersymmetry local.

Supergravity, together with string theory, is one of the most significant developments in theoretical physics. Written by two of the most respected workers in the field, this is the first-ever authoritative and systematic account of supergravity. The book starts by reviewing aspects of relativistic field theory in Minkowski spacetime. After introducing
