Gordon–Martino conjecture for Calogero–Moser and Rouquier families

From papers

Let WW be a complex reflection group, let C{\mathcal{C}} be its Calogero–Moser parameter space, and let κ:CK\kappa:{\mathcal{C}}\rightarrow{\mathcal{K}} be the parameter correspondence, with kk^\sharp the associated Rouquier parameter. Gordon–Martino conjecture. If cCc\in{\mathcal{C}} and k=κ(c)K=Ck=\kappa(c)\in{\mathcal{K}}={\mathcal{C}}, then every Calogero–Moser cc-family is a union of Rouquier kk^\sharp-families. The paper subsequently verifies this assertion in all cases covered by its computations, but the supplied text does not establish it universally.
