Let \(\Sc(\vL)\) be the cyclotomic \(q\)-Schur algebra associated to the Ariki-Koike algebra \(\He_{n,r}\), introduced by Dipper-James-Mathas. In this paper, we consider \(v\)-decomposition numbers of \(\Sc(\vL)\), namely decomposition numbers with respect to the Jantzen filtrations of Weyl modules. We prove, as a \(v\)-analogue of the result obtai...
