Ground Ring of Two Dimensional String Theory
String theories with two dimensional space-time target spaces are characterized by the existence of a “ground ring” of operators of spin (0, 0). By understanding this ring, one can understand the symmetries of the theory and illuminate the relation of the critical string theory to matrix models. The symmetry groups that arise are, roughly, the area preserving diffeomorphisms of a two dimensiona...
متن کاملBoundary Ground Ring in 2D String Theory
The 2D quantum gravity on a disc, or the non-critical theory of open strings, is known to exhibit an integrable structure, the boundary ground ring, which determines completely the boundary correlation functions. Inspired by the recent progress in boundary Liouville theory, we extend the ground ring relations to the case of non-vanishing boundary Liouville interaction known also as FZZT brane i...
متن کاملBoundary Ground Ring in Minimal String Theory
We obtain relations among boundary states in bosonic minimal open string theory using the boundary ground ring. We also obtain a difference equation that boundary correlators must satisfy. email: [email protected], Address after Sep 11, 2005: School of Natural Sciences, Institute for Advanced Study, Princeton, NJ 08540, USA email: [email protected]
متن کاملThe Ground Ring of N = 2 Minimal String Theory
We study the N = 2 string theory or the N = 4 topological string on the deformed CHS background. That is, we consider the N = 2 minimal model coupled to the N = 2 Liouville theory. This model describes holographically the topological sector of Little String Theory. We use degenerate vectors of the respective N = 2 Verma modules to find the set of BRST cohomologies at ghost number zero–the groun...
متن کاملPerturbing the Ground Ring of 2-d String Theory
We use free field techniques in D=2 string theory to calculate the perturbation of the special state algebras when the cosmological constant is turned on. In particular, we find that the “ground cone” preserved by the ring structure is promoted to a three dimensional hyperboloid as conjectured by Witten. On the other hand, the perturbed (1,1) current algebra of moduli deformations is computed c...
