Absolutely strongly star-Hurewicz spaces
A space X is absolutely strongly star-Hurewicz if for each sequence (Un :n ∈ℕ/ of open covers of X and each dense subset D of X, there exists a sequence (Fn :n ∈ℕ/ of finite subsets of D such that for each x ∈X, x ∈St(Fn; Un) for all but finitely many n.

Some properties defined by relative versions of star-covering properties II
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 "easily" prove that the set strong star

Selection principles and covering properties in bitopological spaces [PDF]
Our main focus in this paper is to introduce and study various selection principles in bitopological spaces. In particular, Menger type, and Hurewicz type covering properties like: Almost p-Menger, star p-Menger, strongly star p-Menger, weakly p-Hurewicz,

The Absolutely Strongly Star-Hurewicz Property with Respect to an Ideal
Abstract Aspace X is said to have the absolutely strongly star --Hurewicz (ASSH) property if for each sequence (𝒰 n : n ∈ )of opencovers of

Remarks on strongly star-Hurewicz spaces
A space X is strongly star-Hurewicz if for each sequence (Un : n ∈ N) of open covers of X there exists a sequence (An : n ∈ N) of finite subsets of X such that for each x ∈ X, x ∈ St(An; Un) for all but finitely many n. In this paper, we continue to investigate topological properties of strongly star-Hurewicz spaces.

Some remarks on Pixley-Roy hyperspaces
In this paper, we study cellular-compact, cellular-Lindel\"of, strongly star-Hurewicz, strongly star-Rothberger, strongly star-Menger spaces on hyperspaces with the Pixley-Roy topology.

In this paper we define and investigate nearly Hurewicz spaces and their star version. It is shown that a nearly Hurewicz space fits between Hurewicz and almost Hurewicz spaces.

Strongly countable dimensional compacta form the Hurewicz set
The hyperspaces of strongly countable dimensional compacta of positive dimension and of strongly countable dimensional continua of dimension greater than 1 in the Hilbert cube are homeomorphic to the Hurewicz set of all nonempty countable closed subsets ...

Variations of some star selection properties [PDF]
4th International Conference of Mathematical Sciences (ICMS) -- JUN 17-21, 2020 -- Maltepe Univ, ELECTR NETWORKIn this paper we introduce some new types of star covering properties which we call set (strongly) star Menger, set (strongly) star Rothberger,
