(q,t)-deformed (skew) Hurwitz τ-functions

We follow the general recipe for constructing commutative families of W-operators, which provides Hurwitz-like expansions in symmetric functions (Macdonald polynomials), order to obtain a difference operator example that gives rise (q,t)-deformation earlier studied models. As before, key role is played by an appropriate deformation cut-and-join rotation operator. outline its expression both terms generators quantum toroidal algebra and Macdonald operators.
