Unification of all string models with c < 1 in the framework of generalized Kontsevich model
Kharchev S., Marshakov A., Mironov A., Morozov A., Zabrodin A.
A 1-matrix model which nicely interpolates between double-scaling continuum limits of all multimatrix models, is proposed. The interpolating partition function is always a KP r-function, and always obeys J£ _ x constraint and string equation. This model can therefore be considered as a natural unification of all models of 2D gravity (string models) with с < 1.
