关于图逆半群上的同余格

On lattice of congruences on graph inverse semigroups

Yongle Luo, Zhengpan Wang

摘要:

图逆半群上的同余是最近用下划线图描述的。在此基础上,我们证明了图逆半群上的同余格是上半模的而不是下半模的。

英文摘要:

Congruences on a graph inverse semigroup were recently described in terms of the underline graph. Based on such descriptions, we show that the lattice of congruences on a graph inverse semigroup is upper semimodular but not lower semimodular.
