[HTML][HTML] On T0 spaces determined by well-filtered spaces

X Xu, C Shen, X Xi, D Zhao - Topology and its Applications, 2020 - Elsevier
We first introduce and study two new classes of subsets in T 0 spaces — Rudin sets and WD
sets lying between the class of all closures of directed subsets and that of irreducible closed …

[HTML][HTML] On well-filtered reflections of T0 spaces

C Shen, X Xi, X Xu, D Zhao - Topology and its Applications, 2019 - Elsevier
Following Ershov's method of constructing the d-completion of T 0 spaces, we give a direct
construction of the well-filtered reflection of T 0 spaces. Also, we obtain an elegant …

metastasis (LNM) in laryngeal squamous cell carcinoma (LSCC). Methods LSCC patients …

A complete Heyting algebra whose Scott space is non-sober

X Xu, X Xi, D Zhao - arXiv preprint arXiv:1903.00615, 2019 - arxiv.org
We prove that (1) for any complete lattice $L$, the set $\mathcal{D}(L)$ of all nonempty
saturated compact subsets of the Scott space of $L$ is a complete Heyting algebra (with the …

[HTML][HTML] On topological Rudin's lemma, well-filtered spaces and sober spaces

X Xu, D Zhao - Topology and its Applications, 2020 - Elsevier
Based on topological Rudin's Lemma, we investigate two new kinds of sets – Rudin sets and
well-filtered determined sets in T 0 topological spaces. Using such sets, we formulate and …

[HTML][HTML] Existence of well-filterifications of T0 topological spaces

G Wu, X Xi, X Xu, D Zhao - Topology and its Applications, 2020 - Elsevier
We prove that for every T 0 space X, there is a well-filtered space W ( X ) and a continuous
mapping η X : X ⟶ W ( X ) , such that for any well-filtered space Y and any continuous …

On H-sober spaces and H-sobrifications of T0 spaces

X Xu - Topology and its Applications, 2021 - Elsevier
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. The concepts of …

Objective To investigate the value of radiomics analysis of dual-energy computed tomography
(DECT)–derived iodine maps for preoperative diagnosing cervical lymph nodes (LNs) …

Some open problems on well-filtered spaces and sober spaces

X Xu, D Zhao - Topology and its Applications, 2021 - Elsevier
In the past few years, the research on sober spaces and well-filtered spaces has got some
breakthrough progress. In this paper, we shall present a brief summarizing survey on some of …
