Gordon–Martino conjecture for Calogero–Moser and Rouquier families

About 11 years old · traced to

Let WW be a complex reflection group, let C{\mathcal{C}} be its Calogero–Moser parameter space, and let κ:C→K\kappa:{\mathcal{C}}\rightarrow{\mathcal{K}} be the parameter correspondence, with k♯k^\sharp the associated Rouquier parameter. Gordon–Martino conjecture. If c∈Cc\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 k♯k^\sharp-families. The paper subsequently verifies this assertion in all cases covered by its computations, but the supplied text does not establish it universally.
