Abstract
In this paper, we prove the Regev formula for the characters of the Ariki–Koike algebras by applying the Schur–Sergeev reciprocity between quantum superalgebras and Ariki–Koike algebras. As a corollary, we derive the Regev formula for the characters of the complex reflection group of type , generalizing the Regev formula for the symmetric groups due to A. Regev (2013) [19].
