Noetherian Properties, Large Cardinals, and Independence Around

Lajos Soukup, Zoltán Szentmiklóssy

A base of a topological space is called {\em Noetherian } iff it does not contain an infinite strictly -increasing chain. We show that minimal cardinality of a regular s…

Condensations with extra properties

István Juhász, Jan van Mill, Lajos Soukup

We show that there are locally compact spaces that can be condensed onto separable spaces but not onto compact separable spaces. We also show that for every cardinal there is a…

Cut-and-choose games in topological spaces

Lucas Chiozini, Tamás Csernák, Lajos Soukup

We study transfinite cut-and-choose games on spaces, introducing the {\em point-separating number} and the {\em set membership number} as the ordinal-valued…

Selectively pseudocompact spaces

István Juhász, Lajos Soukup, Zoltán Szentmiklóssy

A novel selection principle was introduced by Dorantes-Aldama and Shakhmatov: a topological space is termed {\em selectively pseudocompact} if for any sequence o…

On the companion of spaces having dense, relatively countable compact subspaces

István Juhász, Lajos Soukup, Zoltán Szentmiklóssy

The notion of "pseudocompactness" was introduced by Hewitt. The concept of relatively countably compact subspaces were explored by Marjanovic to show that a -space is pseudocomp…

Elusive properties of infinite graphs

Tamás Csernák, Lajos Soukup

A graph property is said to be elusive ( evasive) if every algorithm testing this property by asking questions of the form "is there an edge between vertices x and y" requires, in…

Intersection properties of open sets, II.

I. Juhász, Zs. Nagy, Lajos Soukup +1

A topological space is called P_2 ( P_3, P_{<omega} ) if and only if it does not contain two (three, finitely many) uncountable open sets with empty intersection. We show that (i)…
