نویسندگان
چکیده
We review the detailed structure of the large N = 4 superconformal algebra, and construct its BRST operator which constitutes the main object for analyzing N = 4 strings. We then derive the general condition for the nilpotency of the BRST operator and show that there exists a line of critical N = 4 string theories. e-mail address: [email protected] e-mail address: [email protected], [email protected] Permanent address: Department of Physics, Osaka University, Toyonaka, Osaka 560, Japan.

Bosonization 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 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 کاملConstructing Classical and Quantum Superconformal 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 address the question of constructing spacetime N extended superconformal algebras on the boundary of AdS3. Based on a free field realization of an affine SL(2|N/2) current superalgebra residing on the world sheet, we construct explicitly the Virasoro generators and the...
متن کاملSuperconformal current algebras and topological field theories
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 whos...
متن کاملNo N = 4 Strings on Wolf Spaces 1
We generalize the standard N = 2 supersymmetric Kazama-Suzuki coset construction to the N = 4 case by requiring the non-linear (Goddard-Schwimmer) N = 4 quasi-superconformal algebra to be realized on cosets. The constraints that we find allow very simple geometrical interpretation and have the Wolf spaces as their natural solutions. Our results obtained by using components-level superconformal ...
