摘要
给出了将任一1-可扩图分解为阶数较小的1-可扩图的分解方法.得到了有v个顶点(v≥6)非二部1-可扩图的可去耳朵数的紧的上、下界分别为3(v-1)(v-2)/2和3.
An edge deleting decomposition which will decompose a 1-extendable graph into a smaller 1-extendable graph is given. The tight upper and lower bounds of the number of removable ears in a non-bipartite graph on v verties ( v ≥ 6) are determined, which are 3 (v - 1 ) ( v - 2)/2 and 3 respectively.
