Some properties defined by relative versions of star-covering properties II

Bonanzinga, Maddalena; Giacopello, Davide; Maesano, Fortunato (Universitat Politècnica de València, 2023-10-02)

[EN] In this paper we consider some recent relative versions of Menger property called set strongly star Menger and set star Menger properties and the corresponding Hurewicz-type properties. In particular, using [2], we ...
Strong Fréchet properties of spaces constructed from squares and AD families

Chen-Mertens, William; Corral-Rojas, Cesar Ismael; Szeptycki, Paul J. (Universitat Politècnica de València, 2023-10-02)

[EN] We answer questions of Arhangel'skiĭ using spaces defined from combinatorial objects. We first establish further convergence properties of a space constructed from □ ( κ ) showing it is Fréchet-Urysohn for finite sets ...
Partial actions on limit spaces

Losert, Bernd; Richardson, Gary (Universitat Politècnica de València, 2023-10-02)

[EN] G-compactifications of continuous partial actions in the category of limit spaces are considered. In particular, sufficient conditions are given to ensure that (G, X, α) has a largest regular G-compactification.
Fixed points of set-valued mappings in Menger probabilistic metric spaces endowed with an amorphous binary relation

Prasad, Gopi; Deshwal, Sheetal; Srivastav, Rupesh K. (Universitat Politècnica de València, 2023-10-02)

[EN] In this paper, we prove the existence of fixed point results for set-valued mappings in Menger probabilistic metric spaces equipped with an amorphous binary relation and a Hadžić -type t-norm. For the usability of ...
Remarks on fixed point assertions in digital topology, 6

Boxer, Laurence (Universitat Politècnica de València, 2023-10-02)

[EN] This paper continues a series discussing flaws in published assertions concerning fixed points in digital metric spaces.
