摘要
引入序■-半群的(m,n)拟理想、m-左理想、n-右理想的概念,给出它们的生成的表示;证明了序■-半群上任何(m,n)拟理想可以分解为一个m-左理想和一个n-右理想的交,且任何一个极小的(m,n)拟理想可以分解为一个极小m-左理想和一个极小n-右理想的交;给出了(m,n)拟单偏序■-半群的刻画和偏序■-半群拟理想、左理想和右理想的刻画.
In this paper, the concepts of(m,n) quasi-ideals, m- left ideals and n- right ideals of po-Γ- semigroups are introduced. The generation theorems of(m,n) quasi-ideals, m- left ideals and n- right ideals are obtained by every non-emptyset of po-Γ- semigroups. That any(m, n) quasi-ideal of po-Γ- semigroups can be expressed as the intersection of a m- left ideal and a n- right ideal of po-Γ- semigroups is proved. Moreover any minimal(m,n) quasi-ideal of po-Γ- semigroups can be expressed as the intersection of a minimal m- left ideal and a minimal n- right ideal of po-Γ- semigroups. Finally characterizations of(m,n) quasi-simple po-Γ- semigroups are given by(m, n) quasi-ideals. As an application of results of this paper, some results of quasi-ideals, left ideals and right ideals of po-Γ- semigroups are obtained.
