The Shuffle Algebra Revisited

Abstract: In this paper we introduce certain new features of the shuffle algebra of [3] that will allow us to obtain explicit formulas for the isomorphism between its Drinfeld double and the elliptic Hall algebra of [1], [7]. These results are necessary for our work in [4] and [6], where they will be applied to the study of the Hilbert scheme and to computing knot invariants.

“…Unfortunately most of this material is written in a language that is nearly inaccessible to most practitioners of Algebraic Combinatorics. We were fortunate that the two young researchers E. Gorsky and A. Negut, in a period of several months, made us aware of some of the contents of the latter publications as well as the results in their papers ( [14], [19] and [20]) in a language we could understand. The present developments are based on these results.…”

“…The resulting operator, which will be denoted "G km,kn ," turns out to have a variety of surprising properties. In fact, computer exploration led to the discovery (in [2]) that in many instances the symmetric polynomial G km,kn (−1) k(n+1) has a conjectured combinatorial interpretation as an enumerator of certain families of "rational" Parking Functions.One of the most surprising contributions to this branch of Algebraic Combinatorics is a recent deep result [18] of Andrei Negut giving a relatively simple but powerful constant term expression for the action of the operators Q m,n . The reader is referred to the findings concerning the Negut formula that are presented in [2] for the reasons we used the word "powerful" in this context.…”
