Quantum moduli spaces from matrix models
In this paper we show that the matrix model techniques developed by Dijkgraaf and Vafa can be extended to compute quantum deformed moduli spaces of vacua in four dimensional supersymmetric gauge theories. The examples studied give the moduli space of a bulk D-brane probe in geometrically engineered theories, in the presence of fractional branes at singularities.
متن کاملMatrix Models: a Way to Quantum Moduli Spaces
We give the description of discretized moduli spaces (d.m.s.) M g,n introduced in [1] in terms of a discrete de Rham cohomologies for each moduli space Mg,n of a genus g, n being the number of punctures. We demonstrate that intersection indices (cohomological classes) calculated for d.m.s. coincide with the ones for the continuum moduli space Mg,n compactified by Deligne and Mumford procedure. ...
متن کاملMatrix Models and Geometry of Moduli Spaces
We give the description of discretized moduli spaces (d.m.s.) M disc g,n introduced in [1] in terms of discrete de Rham cohomologies for moduli spaces Mg,n. The generating function for intersection indices (cohomological classes) of d.m.s. is found. Classes of highest degree coincide with the ones for the continuum moduli space Mg,n. To show it we use a matrix model technique. The Kontsevich ma...
متن کاملDelzant models of moduli spaces
For every genus g, we construct a smooth, complete, rational polarized algebraic variety DMg together with a normal crossing divisor D = ⋃ Di, such that for every moduli space MΣ(2, 0) of semistable topologically trivial vector bundles of rank 2 on an algebraic curve Σ of genus g there exists a holomorphic isomorphism f : MΣ(2, 0) \ K2 → DMg \ D, where K2 is the Kummer variety of the Jacobian o...
