ITP-UU-03/52, SPIN-03/33 (m, n) ZZ branes and the c = 1 matrix model

چکیده
We argue that the origin of non-perturbative corrections e−2πRnμ in the c = 1 matrix model is (1, n) D-branes of Zamolodchikovs. We confirm this identification comparing the flow of these corrections under the Sine–Liouville perturbation in the two approaches.

We give a geometric interpretation for D-branes in the c = 1 string theory. The geometric description is provided by complex curves which arise in both CFT and matrix model formulations. On the CFT side the complex curve appears from the partition function on the disk with Neumann boundary conditions on the Liouville field (FZZ brane). In the matrix model formulation the curve is associated wit...

The structure of equivariant cohomology in non-abelian localization formulas and topological field theories is discussed. Equivariance is formulated in terms of a nilpotent BRST symmetry, and another nilpotent operator which restricts the BRST cohomology onto the equivariant, or basic sector. A superfield formulation is presented and connections to reducible (BFV) quantization of topological Ya...
