摘要
给出了ω-链族{Ei|i∈I}的O-直并E=∪i∈IEi∪{0}的Munn半群TE的结构,刻画了它的同余格C(TE).证明了它的所有非平凡非泛同余都是O-双单同余,在包含关系下形成一个与正整数在整除关系下反同构的格.
In this paper,the structure of the Munn semigroup TE for a O-direct union E of ω-chains {Ei|i∈I} is given,the congruence lattice C(TE) is described.It is proved that all nontrivial and nonuniversal congruences are all O-bisimple congruences and they form a lattice under inclusion anti-isomorphic to that of all positive integral numbers under division.
