The W-goodness finite-dimensional quotient conjecture
The W-goodness finite-dimensional quotient conjecture
Let be a real reflection group with reflection representation . A positive integer is -good if, for every parameter with , the Cherednik algebra admits a finite-dimensional module of the form , where is an irreducible -submodule of dimension . Let be the distinguished copy of the defining module in the degree- quasiharmonics at parameter . W-goodness quotient conjecture. If is -good, then
is finite-dimensional. The conjecture connects the universal quasiharmonic submodule with the finite-dimensional representations guaranteed by -goodness. The source provides examples of -good integers for types , , , and , but does not establish the conjecture in general.
