Authors: ROGHAYEH HAFEZIEH, MOOHAMMADALI IRANMANESH

Abstract: The IP-graph of a naturally valenced association scheme and some of its properties have been studied recently. In this paper we introduce the bipartite version of this graph for a naturally valenced association scheme (X,S), denoted by BIP(S). We also investigate some of its properties.

Keywords: Association scheme, common divisor graph, prime graph, bipartite divisor graph
