Haver’s near-selection theorem deals with approximate selections of Hausdorff continuous CE-valued mappings defined on $\sigma $-compact metrizable $C$-spaces. In the present paper, we show that it is valid for all paracompact $C$-spaces, which answers in

The aim of this paper is to study fuzzy extensions some covering properties defined by A. V. Arhangel’skii and studied other authors. Indeed, in 2016, paracompact-type properties: C-paracompactness C2-paracompactness. Later, M. Saeed, L. Kalantan H. Alzumi investigated these two properties. In paper, we define notions obtain results about them, particular, prove that are good those Arhangel’skii.

In the title complex, [Cu(C(4)H(5)NO(4))(C(6)H(6)N(2)O)(H(2)O)], conventionally abbreviated Cu(IDA)(4-OXPy)(H(2)O), where IDA is imino-diacetate and 4-OXPy is 4-(hy-droxy-imino-meth-yl)pyridine, the Cu(II) atom exhibits a distorted square-pyramidal coordination geometry, which is constructed from two O atoms and one N atom from a IDA ligand, one N atom from 4-OXPy ligand and one O atom from wat...

This work is devoted to the study of certain cardinality modifications of paracompactness and compactness in the setting of linearly ordered spaces. Some of the concepts treated here have previously been studied by Aquaro [l]1, Gulden [4], Kennison [5], Mansfield [6], Morita [7], and Poppe [9]. On the other hand, the concept of m-boundedness, introduced in §2, is new. Our main results (Theorems...
