Infinitesimal Change of Stable Basis
The purpose of this note is to study the
Maulik-Okounkov K-theoretic stable basis for the Hilbert scheme
of points on the plane, which depends on a "slope" m in
R. When m = a/b is rational, we study the change of
stable basis from slope m-ε to m+ε for small
ε>0, and conjecture that it is related to the
Leclerc-Thibon conjugation in the q-Fock space for
This is part of a wide framework of
connections involving derived categories of quantized Hilbert schemes,
modules for rational Cherednik algebras and Hecke algebras at roots of
