At last,we character the local-strong endomorphisms of the join of two split graphs and prove that quasi-strong endomorphisms of it is local-strong. And we give a condition under which the join of two split graphs forms monoids.
最后以分裂图的连图为研究对象,刻画两个分裂图的连图的局部强自同态,并证明了每个局部强自同态都是拟强的,给出了两个分裂图的连图的所有局部强自同态构成么半群的条件。
