【 摘 要 】

We continue the study of Specht modules labelled by hook bipartitions for the Iwahori-Hecke algebra of type B with e is an element of {3, 4, ...} via the cyclotomic Khovanov- Lauda-Rouquier algebra H-n(Lambda). Over an arbitrary field, we explicitly determine the graded decomposition submatrices for H-n(Lambda) comprising comprising rows corresponding to hook bipartitions. (C) 2019 Elsevier B.V.
