Unification of All String Models with с < 1 in the Framework of Generalized Kontsevich Model
Kharchev S., Marshakov A., Mironov A., Morozov A., Zabrodm A.
A 1-matrix model is proposed, which nicely interpolates between double-scaling continuum limits of all multimatrix models. The interpolating partition function is always a KP r-function and always obeys £-^constraint and string equation. Therefore this model can be considered as a natural unification of all models of 2<i-gravity (string models) with с < 1.
