| 中文摘要: |
| 本文研究图及其强自同态幺半群．首先刻画了图的强自同态幺半群的正则元，然后给出了此幺半群正则的充要条件．这推广了［１］和［２］中关于有限图的强自同态幺半群正则的结果． |
| 英文摘要: |
| Graphs and their strong endomorphism monoids are considered in this paper. First, the regular elements of strong endomorphism monoids of graphs are characterized. Then necessary and sufficient conditions for these monoids to be regular are given. These results generalize that of U.Knauer and Li Weimin about the regularity of strong endomorphism monoids of finite graphs. |
