Bowman, Christopher, Speyer, L. (2019) An analogue of row removal for diagrammatic cherednik algebras. Mathematische Zeitschrift, 293 . pp. 935-955. ISSN 0025-5874. E-ISSN 1432-1823. (doi:10.1007/s00209-018-2222-y) (KAR id:70234)


We prove an analogue of James–Donkin row removal theorems for diagrammatic

Cherednik algebras. This is one of the first results concerning the (graded) decomposition numbers

of these algebras over fields of arbitrary characteristic. As a special case, our results yield a new

reduction theorem for graded decomposition numbers and extension groups for cyclotomic q-Schur
