Towards elliptic deformation of q,t-matrix models

As a necessary step in construction of elliptic matrix models, which preserve the superintegrability property ?char, we suggest an deformation peculiar loci pk?n, play important role precise formulation this property. The suggestion is to define pk?n-loci as functions with right asymptotics at ??i?. If hypothesis correct, one can move substituting Schur and Macdonald characters by GNS study their behavior deformed topological ? loci.
