Path Integration in Two-dimensional Topological Quantum Field Theory

چکیده
A positive, di eomorphism-invariant generalized measure on the space of metrics of a two-dimensional smooth manifold is constructed. We use the term generalized measure analogously with the generalized measures of Ashtekar and Lewandowski and of Baez. A family of actions is presented which, when integrated against this measure give the two-dimensional axiomatic topological quantum eld theories, or TQFT's, in terms of which Durhuus and Jonsson decompose every two-dimensional unitary TQFT as a direct sum.

A Review of Functional Integral Techniques for Low-Dimensional Gauge Theories and Topological Field Theories
We review localization techniques for functional integrals which have recently been used to perform calculations in and gain insight into the structure of certain topological field theories and low-dimensional gauge theories. These are the functional integral counterparts of the Mathai-Quillen formalism, the Duistermaat-Heckman theorem, and the Weyl integral formula respectively. In each case, ...

متن کاملYang-Mills Theory as a Deformation of Topological Field Theory, Dimensional Reduction and Quark Confinement
We prove quark confinement in four-dimensional QCD based on the criterion of area law of Wilson loop. First, Yang-Mills theory with a non-Abelian gauge group G is reformulated as a deformation of a novel topological field theory. Next, a special class of topological field theories is defined by both BRST and anti-BRST exact action corresponding to the maximal abelian gauge leaving the maximal t...
متن کاملLectures on 2D Yang-Mills Theory, Equivariant Cohomology and Topological Field Theories
These are expository lectures reviewing (1) recent developments in two-dimensional YangMills theory and (2) the construction of topological field theory Lagrangians. Topological field theory is discussed from the point of view of infinite-dimensional differential geometry. We emphasize the unifying role of equivariant cohomology both as the underlying principle in the formulation of BRST transf...
متن کاملEquivariant Localization of Path Integrals
We review equivariant localization techniques for the evaluation of Feynman path integrals. We develop systematic geometric methods for studying the semi-classical properties of phase space path integrals for dynamical systems, emphasizing the relations with integrable and topological quantum field theories. Beginning with a detailed review of the relevant mathematical background – equivariant ...
