abstract
Let X be a smooth projectibe curve over a finite field. We consider the Hall algebra H whose basis is formed by isomorphism classes of coherent sheaves on X and whose typical structure constant is the number of subsheaves in a given sheaf belonging to a given isomorphism class and with given isomorphism class of quotient. We study this algebra in detail. It turns out that its structure is strikingly similar to that of quantum affine algebras in their loop realization of Drinfeld. In this analogy the set of simple roots of a semisimple Lie algebra g corresponds to the set of cusp forms on X, the entries of the Cartan matrix of g to the values of Rankin-Selberg L-functions associated to two cusp forms. For the simplest instances of both theories (the curve P^1, the Lie algebra g=sl_2) the analogy is in fact an identity.

The twisted Cherednik spectrum is a q,t-deformation of the polynomial eigenfunctions built from symmetric ground states and weak-composition excitations at q=1.
Non-commutative creation operators B̂_m are built for symmetric polynomials in matrix and Fock representations of W_{1+∞} and affine Yangian algebras.
Type C∨C DAHA and Koornwinder systems mirror type-A Macdonald structures for Hamiltonians, recursions, evaluations and dualities, but lack a usable Noumi-Shiraishi-style universal series and SL(2,Z)-type twisting automorphisms.

Integrable systems inspired by DAHA and DIM algebra: type $C^\vee C$ versus type $A$
