Perverse-filtration and Cherednik-filtration conjecture for compactified Jacobians
Perverse-filtration and Cherednik-filtration conjecture for compactified Jacobians
For coprime positive integers , let be the finite-dimensional simple representation of the rational Cherednik algebra with parameter , let be its spherical part, and let denote the filtration of Proposition CEE. Let the cohomology of the compactified Jacobian of the singularity carry its perverse filtration. Perverse-filtration conjecture. The perverse filtration and the filtration of Proposition CEE agree.
This identification would connect the geometric perverse filtration with the representation-theoretic filtration used to compute torus-knot homology. The source gives no resolution status.
