Gorsky–Negut–Rasmussen conjecture for sheaves on Hilbert schemes
Gorsky–Negut–Rasmussen conjecture for sheaves on Hilbert schemes
Let be a braid on strands. Let be the indicated Hilbert scheme, let be its tautological rank- bundle, and let be a -equivariant coherent sheaf. Gorsky–Negut–Rasmussen conjecture. The sheaf has properties (a)–(e):
(a) as triply graded vector spaces, with the stated grading correspondence;
(b) the action of symmetric functions in corresponds to the action of on the right;
(c) for a braid whose closure is a knot, all act identically and is supported on ;
(d) adding corresponds to tensoring by ;
(e) extends to a sheaf on the whole corresponding to -ified homology. The conjecture was mostly proved in a series of papers by Oblomkov and Rozansky, so its database status is solved.
