关于左C-wrpp半群的加细半格分解

On the Refined Semilattice Decomposition of Left C-wrpp Semigroups

令S是左C-wrpp半群,κ是其上的等价关系,研究一类特殊左C-wrpp半群S的加细半格分解,即κ是S上的同余时,左C-wrpp半群S的加细半格分解,得到左C-wrpp半群的加细半格分解结构的等价刻画.

Let S be a left C-wrpp semigroup, and K an equivalent relation on S. We investigate the refined semilattiee decomposition of a special class of left C-wrpp semigroups, that is, the semilattice left C-wrpp semigroups on which equivalent relation K is a congruence. An equivalent characterization of the refined decomposition is obtained.
