Abstract

We prove a new `runner removal theorem' for qq-decomposition numbers of the level 1 Fock space of type Ae1(1)A^{(1)}_{e-1}, generalising earlier theorems of James--Mathas and the author. By combining this with another theorem relating to the Mullineux map, we show that the problem of finding all qq-decomposition numbers indexed by partitions of a given weight is a finite computation.
