Lectures on 2D YangMills Theory, Equivariant Cohomology and Topological Field Theories
Abstract
These are expository lectures reviewing (1) recent developments in twodimensional YangMills theory, and (2) the construction of topological field theory Lagrangians. Topological field theory is discussed from the point of view of infinitedimensional differential geometry. We emphasize the unifying role of equivariant cohomology both as the underlying principle in the formulation of BRST transformation laws and as a central concept in the geometrical interpretation of topological field theory path integrals.
