摘要:研究了由cut算子定义的多种连续偏序集之间的关系.利用Frink理想的构造证明了偏序集L为s*2-超连续偏序集当且仅当L为F-连续的s1-连续偏序集,进而给出了偏序集L为s*2-超代数偏序集、L为s1-连续的s2-超代数偏序集、L为F-代数的s1-连续偏序集等3种等价条件.

关键词: 偏序集, cut算子, 连续偏序集, 代数偏序集

Abstract: To investigate the relationships among various types of continuous posets defined by the cut operator,this paper uses the construction of Frink ideals to prove that a poset L is s*2-supercontinuous if and only if it is F-continuous and s1-continuous.Furthermore,the equivalence of three descriptions is established:L is s*2-superalgebraic,L is s1-continuous and s2-superalgebraic,and L is L-algebraic and s1-continuous.

Key words: partial order set, cut operator, continuous poset, algebraic continuous poset
