Journal ArticleDOI
Spinning string models on group manifolds with twisted boundary conditions
TL;DR: In particular, massless fermions arise for some non-abelian groups as mentioned in this paper, and the mass spectra of the twisted models are different from those of the corresponding untwisted models.
Journal ArticleDOI
A four-dimensional string
TL;DR: In this article, a modified Green-Schwarz covariant supersymmetric string action was used to construct a free four-dimensional string, which is tachyon-free, ghost-free and Lorentz invariant.
Journal ArticleDOI
Modular invariance of twisted string theories on group-manifolds
TL;DR: In this article, the authors use twisted affine algebra to investigate the modular transformation properties of the partition functions of string theories on group manifolds with twisted boundary conditions and contruct the modular invariant twisted string theories.
