摘要：

In this paper we present a necessary and sufficient condition under which a (combinatorial) morphism between association schemes induces an algebra homomorphism between their scheme rings. We will also discuss scheme ring homomorphisms of naturally valenced association schemes. (C) 2009 Elsevier Inc. All rights reserved.
