The Brst Symmetry of Affine Lie Superalgebras and Non-critical Strings
نویسنده
چکیده
The topological eld theories associated with a ne Lie superalgebras are constructed. Their BRST symmetry is characterised by a Kazama algebra containing spin 1, 2 and 3 operators and closes linearly. Under this symmetry all operators are grouped into BRST doublets. The relation between the models constructed and non-critical string theories is explored.

Lie Superalgebra and Extended Topological Conformal Symmetry in Non - critical W 3 Strings
We obtain a new free field realization of N = 2 super W3 algebra using the technique of quantum hamiltonian reduction. The construction is based on a particular choice of the simple root system of the affine Lie superalgebra sl(3|2)(1) associated with a non-standard sl(2) embedding. After twisting and a similarity transformation, this W algebra can be identified as the extended topological conf...
متن کاملHamiltonian Reduction and Topological Conformal Algebra in c ≤ 1 Non - critical Strings
We study the hamiltonian reduction of affine Lie superalgebra sl(2|1)(1). Based on a scalar Lax operator formalism, we derive the free field realization of the classical topological topological algebra which appears in the c ≤ 1 non-critical strings. In the quantum case, we analyze the BRST cohomology to get the quantum free field expression of the algebra.

Modules over affine Lie superalgebras G are studied, in particular, for G = ̂ OSP (1, 2). It is shown that on studying Verma modules, much of the results in Kac-Moody algebra can be generalized to the super case. Of most importance are the generalized Kac-Kazhdan formula and the Malikov-Feigin-Fuchs construction, which give the weights and the explicit form of the singular vectors in the Verma m...
متن کاملThe BRST Charge for the D̂ ( 2 , 1 ; α ) Non - Linear Quasi - Superconformal Algebra
The quantum BRST charge for the most general, two-dimensional, nonlinear, N = 4 quasi-superconformal algebra D̂(1, 2;α), whose linearisation is the so-called ‘large’ N = 4 superconformal algebra, is constructed. The D̂(1, 2;α) algebra has ̂ su(2)k+ ⊕ ̂ su(2)k− ⊕ û(1) Kač-Moody component, and α = k/k. As a pre-requisite to our construction, we check the D̂(1, 2;α) Jacobi identities and construct a cl...
متن کاملA Proof of Kac-kazhdan Character Formula for Affine Lie Superalgebras
Kac and Kazhdan conjectured a character formula of a simple module with a generic highest weight at the critical level. We prove this formula for the affine Lie superalgebras with symmetrizable Cartan matrices.
