From Virasoro Constraints in Kontsevich ’ s Model to W - constraints in 2 - matrix Models
The Ward identities in Kontsevich-like 1-matrix models are used to prove at the level of discrete matrix models the suggestion of Gava and Narain, which relates the degree of potential in asymmetric 2-matrix model to the form of W-constraints imposed on its partition function.
متن کاملUnitary matrix integrals in the framework of Generalized Kontsevich Model 1 . Brezin - Gross - Witten Model
We advocate a new approach to the study of unitary matrix models in external fields which emphasizes their relationship to Generalized Kontsevich Models (GKM) with non-polynomial potentials. For example, we show that the partition function of the Brezin-Gross-Witten Model (BGWM), which is defined as an integral over unitary N ×N matrices, ∫ [dU ]eTr(J†U+JU†), can also be considered as a GKM wit...

Higher Genus Correlators from the Hermitian One-Matrix Model
We develop an iterative algorithm for the genus expansion of the hermitian N×N one-matrix model (= the Penner model in an external field). By introducing moments of the external field, we prove that the genus g contribution to the mloop correlator depends only on 3g− 2+m lower moments (3g− 2 for the partition function). We present the explicit results for the partition function and the one-loop...
متن کاملGenus one correlation to multi - cut matrix model solutions
We calculate genus one corrections to Hermitian one-matrix model solution with arbitrary number of cuts directly from the loop equation confirming the answer previously obtained from algebro-geometrical considerations and generalizing it to the case of arbitrary potentials.
