Conformal invariance, supersymmetry and string theory
TL;DR: In this article, the BRST method is used to covariantly quantize superstrings, and in particular to construct the vertex operators for string emission as well as the supersymmetry charge.
Journal ArticleDOI
Gravitation and hamiltonian structure in two spacetime dimensions
TL;DR: In this article, a non-trivial analog of gravitation theory in two dimensional spacetime is built upon this fact, with the inverse of the central charge playing the role of the gravitational constant.

Conformal Field Theory and 2D Quantum Gravity
Jacques Distler,Hikaru Kawai +1 more
TL;DR: In this article, the theory of 2D quantum gravity in the usual conformal gauge was solved and the critical exponents for all genera were obtained for the supersymmetric case.

The Geometry of String Perturbation Theory
Eric D'Hoker,Duong H. Phong +1 more
TL;DR: In this paper, recent progress made towards the understanding of closed bosonic and fermionic string perturbation theory, formulated in a Lorentz-covariant way on Euclidean space-time, is devoted to recent progress.
Journal ArticleDOI
W symmetry in conformal field theory
TL;DR: In this article, the authors review various aspects of W algebra symmetry in two-dimensional conformal field theory and string theory and pay particular attention to the construction of W algebras through the quantum Drinfeld-Sokolov reduction and through the coset construction.

Conformally Invariant Quantization of the Liouville Theory.
TL;DR: In this article, the Liouville theory is quantized with use of Fock space methods, an infinite set of charges L/sub n/, n = 0, +- 1,..., is constructed which represents the conformal algebra in two dimensions, and consequences of this algebra are discussed.

The dual string spectrum in Polyakov's quantization (I)
Jean-Loup Gervais,André Neveu +1 more
TL;DR: In this article, the authors considered the quantization of Liouville's equation in a box, with appropriate boundary conditions, as comes out of Polyakov's analysis of the Nambu action.

Dual models as saddle point approximations to Polyakov's quantized string
TL;DR: In this article, it was shown that if the metric becomes singular on the boundary, then Polyakov's quantized string theory has a saddle point, which leads to an off-shell Green function, the S-matrix of which is the standard dual model.
