Conifold Geometries, Matrix Models and Quantum Solutions
This paper is a continuation of hepth/0507224 where open topological B-models describing D-branes on 2-cycles of local Calabi–Yau geometries with conical singularities were studied. After a short review, the paper expands in particular on two aspects: the gauge fixing problem in the reduction to two dimensions and the quantum matrix model solutions.
متن کاملConstructing Gauge Theory Geometries from Matrix Models
We use the matrix model — gauge theory correspondence of Dijkgraaf and Vafa in order to construct the geometry encoding the exact gaugino condensate superpotential for the N = 1 U(N) gauge theory with adjoint and symmetric or anti-symmetric matter, broken by a tree level superpotential to a product subgroup involving U(Ni) and SO(Ni) or Sp( Ni 2 ) factors. The relevant geometry is encoded by a ...
متن کاملBernoulli matrix approach for matrix differential models of first-order
The current paper contributes a novel framework for solving a class of linear matrix differential equations. To do so, the operational matrix of the derivative based on the shifted Bernoulli polynomials together with the collocation method are exploited to reduce the main problem to system of linear matrix equations. An error estimation of presented method is provided. Numerical experiments are...
متن کاملConifold Geometries, Topological Strings and Multi–matrix Models
We study open B-model representing D-branes on 2-cycles of local Calabi–Yau geometries. To this end we work out a reduction technique linking D-branes partition functions and multi-matrix models in the case of conifold geometries so that the matrix potential is related to the complex moduli of the conifold. We study the geometric engineering of the multi-matrix models and focus on two-matrix mo...
