New dynamic fixed point results in Menger spaces [PDF]

open access: yesSurveys in Mathematics and its Applications, 2023
The objective of this paper is to generalize and improve some results in fixed point theorems in both complete metric space and Menger space. These results are generalizations of the analogous ones recently proved by Khojasteh [5], Demma [1], Yildirim ...

On variants of θ-Menger spaces

open access: yesFilomat, 2023
In this paper we further study ?-Menger, ?-almost Menger and ?-weakly Menger properties [13] and investigate their relationships with other selective covering properties. We prove that in extremally disconnected semi-regular spaces, the properties viz.

Zirkuläre, Photogeschützte mRNA für Lichtinduzierte Aktivierung der Translation zu späten Zeitpunkten

open access: yesAngewandte Chemie, EarlyView.
Eine klickbare, photogeschützte 5′‐Kappe (CyCliCap) zur Herstellung von zyklischer, Click‐Cap enthaltender mRNA (Cyclic Click Cap‐mRNA), die bis zur Bestrahlung beachtlich stabil und translational stumm ist, ermöglicht die Aktivierung der Translation in Zellen zu späten Zeitpunkten mittels Lichts. ZUSAMMENFASSUNG mRNA ist eine neue Impfstofftechnologie

Kannan-type cyclic contraction results in $2$-Menger space [PDF]

open access: yesMathematica Bohemica, 2016
In this paper we establish Kannan-type cyclic contraction results in probabilistic 2-metric spaces. We use two different types of $t$-norm in our theorems. In our first theorem we use a Hadzic-type $t$-norm.

Fixed points of set-valued mappings in Menger probabilistic metric spaces endowed with an amorphous binary relation

open access: yesApplied General Topology, 2023
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.

An End Degree for Digraphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT In this paper we define a degree for ends of infinite digraphs. The well‐definedness of our definition in particular resolves a problem by Zuther. Furthermore, we extend our notion of end degree to also respect, among others, the vertices dominating the end, which we denote as combined end degree.

Some remarks on almost Menger spaces and weakly Menger spaces

open access: yesPublications de l'Institut Mathematique, 2015
A space X is almost Menger (weakly Menger) if for each sequence (Un : n ? N) of open covers of X there exists a sequence (Vn : n ? N) such that for every n ? N, Vn is a finite subset of Un and ?n?N ?{V : V ? Vn} = X (respectively, ?n?N ?{V : V ? Vn} = X).

On the definability of Menger spaces which are not σ-compact

open access: yesTopology and its Applications, 2017
Hurewicz proved completely metrizable Menger spaces are /sigma-compact. We extend this to Cech-complete Menger spaces and consistently to projective Menger metrizable spaces. On the other hand, it is consistent that there is a co-analytic Menger space that is not /sigma-compact.
