The PI Property of Graded Hecke Algebras
Gehles, Katrin E
Original · EN
We show that graded Hecke algebras are PI algebras if and only if they are finitely generated over their centres if and only if the deformation parameters tᵢ are zero for all i=1,,N. This generalises a result for symplectic reflection algebras by Etingof - Ginzburg and Brown - Gordon.
