The Menger property for infinite ordered sets
Order, 1988For the definitions of cutset, disjoint family and Menger family as well as a statement of Menger's theorem see the review above (Zbl 0678.06001). In this paper it is shown that if an ordered set P contains at most k pairwise disjoint maximal chains, where k is finite, then every finite family of maximal chains in P has a cutset of size at most k.

On the Alster, Menger and D-type covering properties
Quaestiones Mathematicae, 2019In this paper we give new characterizations for almost Menger and weakly Menger spaces by neighborhood assignments and dene a natural weakening of almost D-spaces and weakly D-spaces. We discuss the relationships among the properties "D-type", "Menger", "Alster", and the weak versions of these properties in Lindelof spaces.Key words: Menger spaces ...

The PT-order, minimal cutsets and menger property
Order, 1989For a poset \({\mathcal P}=(P,\leq)\) the associated PT-order is the reflexive and transitive binary relation \(\trianglelefteq\) in which \(a\trianglelefteq b\) holds if every maximal chain of \({\mathcal P}\) which passes through a also passes through b.

On weaker forms of Menger, Rothberger and Hurewicz properties
2009Summary: We introduce new star selection principles defined by neighbourhoods and stars which are weaker versions of the Menger, Rothberger and Hurewicz properties; in particular the properties introduced are between strong star versions and star versions of the corresponding properties defined in [\textit{L. D. Kočinac}, Publ. Math. 55, No.~3--4, 421--

Consonant spaces of countable type and the Menger property
Topology and its ApplicationsIf a topological space \(X\) is consonant and either of weak closed countable type or regular and of countable type then \(X\) has property P which in turn is equivalent to the Menger property at infinity provided that \(X\) is completely regular. The product of countably many spaces having property P also has property P.
