Abstract

Recently Brundan, Kleshchev and Wang introduced a Z\Z-grading on the Specht modules of the degenerate and non-degenerate cyclotomic Hecke algebras of type G(,1,n)G(\ell,1,n). In this paper we show that induced Specht modules have an explicit filtration by shifts of graded Specht modules. This proves a conjecture of Brundan, Kleshchev and Wang.
