Extremally disconnected sets in groups [PDF]
Proceedings of the American Mathematical Society, 1975 It is shown that every extremally disconnected compact set in a LCA group is an S H SH -set.

Homogeneous Subspaces of Products of Extremally Disconnected Spaces [PDF]
Topology and its Applications, 2018 Homogeneous countably compact spaces $X$ and $Y$ whose product $X\times Y$ is not pseudocompact are constructed. It is proved that all compact subsets of homogeneous subspaces of the third power of an extremally disconnected space are finite.

Advances in Fuzzy Systems, 2022 In this paper, we introduce fuzzy nano (resp. δ, δS, P and Z) locally closed set and fuzzy nano (resp. δ, δS, P and Z) extremally disconnected spaces in fuzzy nano topological spaces. Also, we introduce some new spaces called fuzzy nano (resp.

A Topological Approach to Full Belief [PDF]
J Philos Logic, 2018 Stalnaker (Philosophical Studies, 128(1), 169–199 2006) introduced a combined epistemic-doxastic logic that can formally express a strong concept of belief, a concept of belief as ‘subjective certainty’.

A homogeneous extremally disconnected countably compact space
Topology and Its Applications, 1987 It is well known that no infinite homogeneous space is both compact and extremally disconnected. (Since there are infinite compact homogeneous spaces and infinite extremally disconnected homogeneous spaces, it is the combination of compactness and ...

A study of extremally disconnected topological spaces [PDF]
Bulletin of Mathematical Sciences, 2011 Throughout, all spaces are assumed to be Tychonoff. A space \(X\) is \textit{extremally disconnected} (\textit{e.d.}~for short) if open subsets of \(X\) have open closures. Any discrete space is a prototypical example of an e.d.~space, though a plethora of non-discrete extremally disconnected spaces is present in mathematics. Let us just mention a fact

Dynamical systems on compact extremally disconnected spaces
Topology and Its Applications, 1991 We consider extremally disconnected compact spaces together with the semigroups of all self- embeddings and the groups of all autohomeomorphisms. The characterizations of minimality and ergodicity of these dynamical systems are given.

Results about the Alexandroff duplicate space
Applied General Topology, 2016 In this paper, we present some new results about the Alexandroff Duplicate Space. We prove that if a space X has the property P, then its Alexandroff Duplicate space A(X) may not have P, where P is one of the following properties: extremally ...

The k-Extremally Disconnected Spaces as Projectives
Canadian Journal of Mathematics, 1964 The letter k denotes an infinite cardinal. A space is a compact Hausdorff space unless otherwise indicated. A space is called extremally disconnected (k-extremally disconnected) if it is the Stone space for a complete (k-complete) Boolean algebra.
