| Research Abstract |
A category of association schemes was defined and some notions were understood categorically. Clifford theory of association schemes and their strongly normal closed subsets was proved. Also a dual, induction and restriction are exchanged, of Clifford theory of association schemes and their algebraic fusions was proved. Some Terwilliger algebras and integral standard generalized table algebras were obtained.
