Sober topological molecular lattices

Northeastern Mathematical Journal 2003年 第3期19卷 254-258页
作者: 张德学 李永明 Department of Mathematics Sichuan University Chengdu 610064 Department of Mathematics Shannxi Normal University Xi'an 710062 topological molecular lattice (TML) is a pair (L r) where L is a completely distributive lattice and T is a subframe of L. There is an obvious forgetful functor from the category TML of TML's to the category Loc of locales. In this note it is showed that this forgetful functor has a right adjoint. Then by this adjunction a special kind of topological molecular lattices called sober topological molecular lattices is introduced and investigated.
A topological molecular lattice (TML) is a pair (L, r), where L is a completely distributive lattice and T is a subframe of L. There is an obvious forgetful functor from the category TML of TML’s to the category Loc ... 详细信息

In [6,11], A theory of pointwise pseudo-quasi-metrics was based on completely distributive lattices. In this paper a product pointwise p.q. metric function is constructed on the product of countably many molecular lat... 详细信息
