摘要：
Splitters are introduced to capture the meaning of barriers in graphs having a perfect internal matching. The factor-critical property is extended in a natural way to accommodate such graphs, and a characterization of factor-critical graphs is given in the new context. Two Tutte type theorems are presented for open graphs with perfect internal matchings, one on maximal splitters, and the other on maximal inaccessible splitters. (C) 2004 Elsevier B.V.
