1 String as a Topological Model
نویسنده
چکیده
The discrete states in the c = 1 string are shown to be the physical states of a certain topological sigma model. We define a set of new fields directly from c = 1 variables, in terms of which the BRST charge and energy-momentum tensor are rewritten as those of the topological sigma model. Remarkably, ground ring generator x turns out to be a coordinate of the sigma model. All of the discrete states realize a graded ring which contains ground ring as a subset.

Topological Structure in ĉ = 1 Fermionic String Theory
ĉ = 1 fermionic string theory, which is considered as a fermionic string theory in two dimension, is shown to decompose into two mutually independent parts, one of which can be viewed as a topological model and the other is irrelevant for the theory. The physical contents of the theory is largely governed by this topological structure, and the discrete physical spectrum of ĉ = 1 string theory i...
متن کاملOn the equivalence of fermionic string to bosonic string in two dimensions
Two-dimensional fermionic string theory is shown to have a structure of topological model, which is isomorphic to a tensor product of two topological ghost systems independent of each other. One of them is identified with c = 1 bosonic string theory while the other has trivial physical contents. This fact enables us to regard two-dimensional fermionic string theory as an embedding of c = 1 boso...
متن کاملv 1 2 5 N ov 1 99 3 EFI - 93 - 66 November 1993 Topological Strings and QCD in Two Dimensions
I present a new class of topological string theories, and discuss them in two dimensions as candidates for the string description of large-N QCD. The starting point is a new class of topological sigma models, whose path integral is localized to the moduli space of harmonic maps from the worldsheet to the target. The Lagrangian is of fourth order in worldsheet derivatives. After gauging worldshe...
متن کاملLarge N 2D Yang-Mills Theory and Topological String Theory
We describe a topological string theory which reproduces many aspects of the 1/N expansion of SU(N) Yang-Mills theory in two spacetime dimensions in the zero coupling (A = 0) limit. The string theory is a modified version of topological gravity coupled to a topological sigma model with spacetime as target. The derivation of the string theory relies on a new interpretation of Gross and Taylor’s ...
متن کاملMonopole-Based Scenarios of Confinement and Deconfinement in 3D and 4D
This review discusses confinement, as well as the topological and critical phenomena, in the gauge theories which provide the condensation of magnetic monopoles. These theories include the 3D SU(N ) Georgi-Glashow model, the 4D [U(1)]N−1-invariant compact QED , and the [U(1)]N−1-invariant dual Abelian Higgs model. After a general introduction to the string models of confinement, an analytic des...
