内部邻域结构II:闭包和闭态射

Internal Neighbourhood Structures II: Closure and closed morphisms

Partha Pratim Ghosh

摘要:

内部preneighborhood空间内的任何一个有限的余积和适当的因式分解结构是第一次介绍了在我以前的文件。提出了内部预邻域空间上的一种闭包运算,并研究了闭态射及其紧密同盟。因此,它介绍了几个众所周知的类的拓扑空间的preneighborhood空间的类似物。本文建立了这些空间的一些初步性质。本文的结果表明,preneighborhood系统是更一般的闭包算子,方便地允许识别性质的态射类独立的连续态射诱导闭包算子。

英文摘要:

Internal preneighbourhood spaces inside any finitely complete category with finite coproducts and proper factorisation structure were first introduced in my earlier paper. This paper proposes a closure operation on internal preneighbourhood spaces and investigates closed morphisms and its close allies. Consequently it introduces analogues of several well known classes of topological spaces for preneighbourhood spaces. Some preliminary properties of these spaces are established in this paper. The results of this paper exhibit preneighbourhood systems are more general than closure operators and conveniently allows identifying properties of classes of morphisms independent of continuity of morphisms with respect to induced closure operators.
