Two-Dimensional String Theory, Topological Field Theories and the Deformed Matrix Model
In this paper the c = 1 string theory is studied from the point of view of topological field theories. Calculations are done for arbitrary genus. A change in the prescription is proposed, which reproduces the results of the 1/x deformed matrix model. It is proposed that the deformed matrix model is related to a D-series Landau-Ginzburg superpotential. CERN-TH.7155/94 January 1994
متن کاملNoncommutative Cohomological Field Theories and Topological Aspects of Matrix models
We study topological aspects of matrix models and noncommutative cohomological field theories (N.C.CohFT). N.C.CohFT have symmetry under the arbitrary infinitesimal noncommutative parameter θ deformation. This fact implies that N.C.CohFT possess a less sensitive topological property than K-theory, but the classification of manifolds by N.C.CohFT has a possibility to give a new view point of glo...
متن کاملTopological field theory interpretation of string topology
The string bracket introduced by Chas and Sullivan is reinterpreted from the point of view of topological field theories in the Batalin-Vilkovisky or BRST formalisms. Namely, topological action functionals for gauge fields (generalizing Chern-Simons and BF theories) are considered together with generalized Wilson loops. The latter generate a (Poisson or Gerstenhaber) algebra of functionals with...
متن کاملMatrix model and string field theory
In this short note we would like to show the relation between the cubic open string field theory for N D-instantons and the string field theory in the presence of the background B field.
متن کاملMatrix Model from String Field Theory
We show that the boundary string field theory (BSFT) on unstable D0-branes in 2d string theory is equivalent to the double scaled c = 1 matrix model (i.e. quadratic action), even though we naively expect many interaction terms in BSFT. It is checked that S-matrices are trivial in the open string theory on the D0-branes. We discuss how to take the closed string decoupling limit in our model in o...
