关于H-sober空间和$T_0$空间的H-sobrification

On H-sober spaces and H-sobrifications of $T_0$ spaces

Xiaoquan Xu

摘要:

本文给出了$d$ -空间、清醒空间和良滤空间的统一方法,并给出了处理所有这些空间的一般框架。对于子集系统H,建立了H-sober空间和超H-sober空间的理论,给出了$T_0$空间的H-sobrification和超H-sobrification的直接构造.因此,所有H-sober空间的范畴在$\mathbf{Top}_0$中是反射的,并且所有超H-sober空间的范畴在$\mathbf{Top}_0$中也是反射的,如果H具有自然性质(称为性质M)。证明了H-sobrification保持$T_0$空间的有限积,当H具有性质M时,超H-sobrification保持$T_0$空间的有限积.

英文摘要:

In this paper, we provide a uniform approach to $d$-spaces, sober spaces and well-filtered spaces, and develop a general framework for dealing with all these spaces. For a subset system H, the theory of H-sober spaces and super H-sober spaces is established, and a direct construction of the H-sobrifcations and super H-sobrifications of $T_0$ spaces is given. Therefore, the category of all H-sober spaces is reflective in $\mathbf{Top}_0$, and the category of all super H-sober spaces is also reflective in $\mathbf{Top}_0$ if H has a natural property (called property M). It is shown that the H-sobrification preserves finite products of $T_0$ spaces, and the super H-sobrification preserves finite products of $T_0$ spaces if H has property M.
