Hamiltonian Reduction and Topological Conformal Algebra in c ≤ 1 Non - critical Strings

چکیده
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.

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 کاملTopological Strings from WZW Models
We show that the BRST structure of the topological string is encoded in the “small” N = 4 superconformal algebra, enabling us to obtain, in a non-trivial way, the string theory from hamiltonian reduction of A(1|1). This leads to the important conclusion that not only ordinary string theories, but topological strings as well, can be obtained, or even defined, by hamiltonian reduction from WZW mo...
متن کاملDEVELOPMENT IN STRING THEORY
The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...
متن کاملNon - critical string field theory for 2 d quantum gravity coupled to ( p , q ) – conformal fields
Non-critical string field theory for 2d quantum gravity coupled to (p,q)–conformal fields Abstract We propose a non-critical string field theory for 2d quantum gravity coupled to (p,q) conformal fields. The Hamiltonian is described by the generators of the W p algebra, and the Schwinger-Dyson equation is equivalent to a vacuum condition imposed on the generators of W p algebra.

We prove that critical and subcritical N = 2 string theory gives a realization of an N = 2 superfield extension of the topological conformal algebra. The essential observation is the vanishing of the background ghost charge. The N = 2 superstring introduced by Ademollo et. al. [1,2,3,4,5] has the critical dimension 2, there are no transverse degrees of freedom, the physical spectrum contains a ...
