NonAbelian Wrepresentation for GKM
Abstract
Wrepresentation is a miraculous possibility to define a nonperturbative (exact) partition function as an exponential action of somehow integrated Ward identities on unity. It is well known for numerous eigenvalue matrix models, when the relevant operators are of a kind of Woperators: for the Hermitian matrix model with the Virasoro constraints, it is a W_{3}like operator, and so on. We extend this statement to the monomial generalized Kontsevich models (GKM), where the new feature is appearance of an ordered Pexponential for the set of noncommuting operators of different gradings.
