研究直径是2的图和直径是3的树的生成母图的导出匹配可扩性;给出了一类导出匹配可扩的拟轮图,并研究了直径是3的树加边的导出匹配可扩性.
Here is the induced matching extendability of the graphs with diameter 2 studied with one class of induced matching extendability of the quasi-wheel graphs presented and the induced matching extendability of the spanning supergraph of trees with diameter 3 studied.
