On spaces with star kernel Menger

open access: yesActa Mathematica Hungarica, 2023
Given a topological property $\mathcal{P}$, a space $X$ is called star-$\mathcal{P}$ if for any open cover $\mathcal{U}$ of the space $X$, there exists a set $Y\subseteq X$ with property $\mathcal{P}$ such that $St(Y,\mathcal{U})=X$; the set $Y$ is ...

On set star-Menger spaces

Quaestiones Mathematicae, 2023
In this paper, we prove that the product of a set star-Menger space with a compact space is a rectangular set star-Menger. We also  provide an example of Tychonoff pesudocompact set star-Menger space which is not set strongly starMenger. The above mentioned  results answer two questions of [14].

On strong Menger-connectivity of star graphs

open access: yesDiscrete Applied Mathematics, 2003
Motivated by parallel routing in networks with faults, we study the following graph theoretical problem. Let G be a graph of minimum vertex degree d. We say that G is strongly Menger-connected if for any copy Gf of G with at most d−2 nodes removed, every
