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
A Relation Between Tree Amplitudes of Closed and Open Strings
TL;DR: In this article, the authors derive a formula which expresses any closed string tree amplitude in terms of a sum of the products of appropriate open string tree amplitudes, which is applicable to the heterotic string as well as to the closed bosonic string and type II superstrings.

Topological sigma models
TL;DR: A variant of the usual supersymmetric nonlinear sigma model is described in this article, governing maps from a Riemann surface to an arbitrary almost complex manifold, which possesses a fermionic BRST-like symmetry, conserved for arbitrary Σ, and obeying Q 2 = 0.
Journal ArticleDOI
Target space duality in string theory
TL;DR: In this paper, target space duality and discrete symmetries in string theory are reviewed in different settings, and the authors present a generalization of the duality to string theory.

Double Field Theory
Chris Hull,Barton Zwiebach +1 more
TL;DR: In this article, a theory of massless fields on the doubled torus was constructed, which includes usual and dual diffeomorphisms, together with a T-duality acting on fields that have explicit dependence on the torus coordinates and the dual coordinates.

Nonabelian Bosonization in Two-Dimensions
TL;DR: In this article, a non-abelian generalization of the usual formulas for bosonization of fermions in 1+1 dimensions is presented, which is equivalent to a local bose theory which manifestly possesses all the symmetries of the fermi theory.

A Course in Arithmetic
TL;DR: In this article, the theorem on arithmetic progressions modular forms is proved for finite fields p-adic fields Hilbert symbol quadratic forms over Qp, and over Q integral quadratics forms with discriminant +-1.

Factorizable dual model of pions.
André Neveu,John H. Schwarz +1 more
TL;DR: In this paper, a dual-resonance model of mesons is constructed through the use of creation and annihilation operators having simple anticommutation properties as well as harmonic-oscillator type operators of the conventional model.

On Unitary ray representations of continuous groups
TL;DR: In this article, the inner product of two rays is introduced, and the transition probability from a state f to a state g is (f, I)'2 where f, g are representatives of the rays f and g respectively.
