Morita equivalence for cyclotomic Birman-Murakami-Wenzl algebras

In this talk, we give a necessary and sufficient condition on the parameters of the cyclotomic BMW algebra being singular over an arbitrary field. This gives the Morita equivalence between the cyclotomic BMW algebra and the direct sum of some Ariki-koike algebras if the parameters are non-singular over an arbitrary field.
