Decomposition numbers for weight 3 blocks of Iwahori--Hecke algebras of type B

Matthew Fayers, Lorenzo Putignano

Published 2024-01-11Version 1

Let B be a weight-$3$ block of an Iwahori--Hecke algebra of type B over any field. We develop the combinatorics of B to prove that the decomposition numbers for B are all 0 or 1.
