Some Results on P4-equipackable Multigraphs
摘要/Abstract
摘要：
若多重图M的任意极大H-填充均是它的最大H-填充，则称M是H-等可填充的多重图.分析了不含自环，且H为P4时的等可填充多重图. 刻画了当多重图的底图为C4，C5和C6时的P4-等可填充多重图的边重数之间需满足的关系，还刻画了不含圈的最长路为3的P4-等可填充多重图.
Abstract：
Multigraph M is called H-equipackable if any maximal H-packing is also a maximum H-packing. We mainly consider P4-equipackable multigraphs without loops. We obtain the relation between edges and multiplicity in the P4-equipackable multigraphs whose basic graphs are isomorphic to C4, C5, C6, and also characterize P4-equipackable multigraphs which contain paths of maximal length 3 without cycles.
