# KLEINIAN SINGULARITIES AND THE GROUND RING OF C=1 STRING THEORY

@article{Ghoshal1992KLEINIANSA, title={KLEINIAN SINGULARITIES AND THE GROUND RING OF C=1 STRING THEORY}, author={Debashis Ghoshal and Dileep P. Jatkar and Sunil Mukhi}, journal={Nuclear Physics}, year={1992}, volume={395}, pages={144-166} }

We investigate the nature of the ground ring of c = 1 string theory at the special ADE points in the c = 1 moduli space associated to discrete subgroups of SU(2). The chiral ground rings at these points are shown to define the ADE series of singular varieties introduced by Klein. The non-chiral ground rings relevant to closed-string theory are 3 real dimensional singular theory are 3 real dimensional singular varieties obtained as U(1) quotients of the kleinian varieties. The unbroken…

We review some of the recent progress in the continuum formulation of two-dimensional string theory, i.e. two-dimensional quantum gravity coupled to $c=1$ matter. Special attention is devoted to the…

Topological B-Model, Matrix Models, $\hat{c}=1$ Strings and Quiver Gauge Theories

We study topological and integrable aspects of = 1 strings. We consider the circle line theories 0A and 0B at particular radii, and the super affine theories at their self-dual radii. We construct…

Matrix model and time-like linear dilaton matter

- Physics

We consider a matrix model description of the 2d string theory whose matter part is given by a time-like linear dilaton CFT. This is equivalent to the c = 1 matrix model with a deformed, but very…

Closed string tachyons, flips and conifolds

Following the analysis of tachyons and orbifold flips described in hep-th/0412337, we study nonsupersymmetric analogs of the supersymmetric conifold singularity and show using their toric geometry…
