Abstract

The Terwilliger algebras of association schemes over an arbitrary field F were briefly called the Terwilliger F-algebras of association schemes in [Citation9]. In this paper, the Terwilliger F-algebras of direct products of group divisible association schemes are studied. The centers, the semisimplicity, the Jacobson radicals and their nilpotent indices, the Wedderburn-Artin decompositions of the Terwilliger F-algebras of direct products of group divisible association schemes are obtained.
