Superconformal current algebras and topological field theories
نویسنده
چکیده
Topological conformal field theories based on superconformal current algebras are constructed. The models thus obtained are the supersymmetric version of the G/G coset theories. Their topological conformal algebra is generated by operators of dimensions 1, 2 and 3 and can be regarded as an extension of the twisted N = 2 superconformal algebra. These models possess an extended supersymmetry whose generators are exact in the topological BRST cohomology.

93 N = 2 Supersymmetric Integrable Models and Topological Field Theories
These lectures review some of the basic properties of N = 2 superconformal field theories and the corresponding topological field theories. One of my basic aims is to show how the techniques of topological field theory can be used to compute effective LandauGinzburg potentials for perturbed N = 2 superconformal field theories. In particular, I will briefly discuss the application of these ideas...
متن کاملOn Quantum Field Theories
We derive unitarity restrictions on the scaling dimensions of primary quantum operators in a superconformal quantum field theory, in d =3, 4, 5, 6. 1. Introduction Whereas classical massless field theories are often conformally invariant, the same is rarely true of their quantum counterparts. To define a quantum field theory, you need to specify both a Lagrangian and a cutoff. The cutoff introd...
متن کاملSuperconformal Algebras on the Boundary of AdS3
Motivated by recent progress on the correspondence between string theory on anti-de Sitter space and conformal field theory, we provide an explicit construction of an infinite dimensional class of superconformal algebras on the boundary of AdS3. These space-time algebras are N extended superconformal algebras of the kind obtainable by hamiltonian reduction of affine SL(2|N/2) current superalgeb...
متن کاملBosonization of a Topological Coset Model and Non-critical String Theory
We analyze the relation between a topological coset model based on super SL(2, R)/U(1) coset and non-critical string theory by using free field realization. We show that the twisted N = 2 algebra of the coset model can be naturally transformed into that of noncritical string. The screening operators of the coset models can be identified either with those of the minimal matters or with the cosmo...
متن کاملDynkin Diagrams of Cp
We investigate N = 2 supersymmetric sigma model orbifolds of the sphere in the large radius limit. These correspond to N = 2 superconformal field theories. Using the equations of topological-anti-topological fusion for the topological orbifold, we compute the generalized Dynkin diagrams of these theories i.e., the soliton spectrum which was used in the classification of massive superconformal t...
