G/G- Topological Field Theories by Cosetting Gk.

G/G topological field theories based on G k WZW models are constructed and studied. These coset models are formulated as Complex BRST cohomology in G c k , the complexified level k current algebra. The finite physical spectrum corresponds to the conformal blocks of G k .The amplitudes for G/G theories are argued to be given in terms of the G k fusion rules. The Complex BRST cohomology is found ...

Balanced Topological Field Theories

We describe a class of topological field theories called “balanced topological field theories.” These theories are associated to moduli problems with vanishing virtual dimension and calculate the Euler character of various moduli spaces. We show that these theories are closely related to the geometry and equivariant cohomology of “iterated superspaces” that carry two differentials. We find the ...

Topological Quantum Field Theories

We intruduce a new invariant for σ models (and foliations more generally) using the even pairing between K-homology and cyclic homology. We try to calculate it for the simplest case of foliations, namely principal bundles. We end up by discussing some possible physical applications primarily in Quantum Gravity and M-Theory. PACS classification: 11.10.-z; 11.15.-q; 11.30.-Ly

Topological Quantum Field Theories

Following my plenary lecture on ICMP2000 I review my results concerning two closely related topics: topological quantum field theories and the problem of quantization of gauge theories. I start with old results (first examples of topological quantum field theories were constructed in my papers in late seventies) and I come to some new results, that were not published yet.

Topological Quantum Field Theories

In this article, written primarily for physicists and geometers, we introduce the notion of TQFT, orbifold, and then we survey the construction of TQFTs originating from orbifolds such as Chen-Ruan cohomology and orbifold string topology.
