@article{Baulieu1989TheTS, title={The topological sigma model}, author={Laurent Baulieu and Isadore Manuel Singer}, journal={Communications in Mathematical Physics}, year={1989}, volume={125}, pages={227-237} }

We obtain the invariants of Witten's topologicalσ-model by gauge fixing a topological action and using BRST symmetry. The fields and the BRST formalism are interpreted geometrically.

Topological models on the lattice and a remark on string theory cloning

- Physics
- 1992

The addition of a topological model to the matter content of a conventional closed-string theory leads to the appearance of many, perturbatively-decoupled spacetime worlds. We illustrate this by…

Poisson-Sigma Models

We investigate the Poisson-Sigma model on the classical and quantum level. In the classical analysis we show how this model includes various known two-dimensional field theories. Then we perform the…

Two-dimensional Yang-Mills Theory and Topological Field Theory

- Physics
- 1995

Two-dimensional Yang-Mills theory (YM2) is often dismissed as a trivial system. In fact it is very rich mathematically and might be the source of some important lessons physically.

In this article we will examine a "generalized topological sigma model." This so-called "generalized topological sigma model" is the M-Theoretic analog of the standard topological sigma model of…

A twisted version of four dimensional supersymmetric gauge theory is formulated. The model, which refines a nonrelativistic treatment by Atiyah, appears to underlie many recent developments in…

A variant of the usual supersymmetric nonlinear sigma model is described, governing maps from a Riemann surfaceΣ to an arbitrary almost complex manifoldM. It possesses a fermionic BRST-like symmetry,…

Definitions. A parametrized (pseudo holomorphic) J-curve in an almost complex manifold (IS, J) is a holomorphic map of a Riemann surface into Is, say f : (S, J3 ~(V, J). The image C=f(S)C V is called…
