摘要
Let R+ (2k) be the set of all bicyclic graphs on 2k(k greater than or equal to 2) vertices with perfect matchings. In this paper, we discuss some properties of the connected graphs with perfect matchings, and then determine graphs with maximal index in R+ (2k). (C) 2004 Elsevier B.V. All rights reserved.
