Cellular-compact and cellular-Lindelöf on hyperspaces
The generalized metric properties on hyperspaces with the Pixley-Roy topology and the Vietoris topology have been studied by many authors. They considered several generalized metric properties and studied the relation between a space $X$ satisfying such ...

Disconnectedness properties of Hyperspaces
Let $X$ be a Hausdorff space and let $\mathcal{H}$ be one of the hyperspaces $CL(X)$, $\mathcal{K}(X)$, $\mathcal{F}(X)$ or $\mathcal{F}_n(X)$ ($n$ a positive integer) with the Vietoris topology. We study the following disconnectedness properties for $\mathcal{H}$: extremal disconnectedness, being a $F^\prime$-space, $P$-space or weak $P$-space and ...

On C -embeddedness of hyperspaces
\(\mathcal{K}(X)\) is the hyperspace of non-empty closed and compact sets and \(\mathcal{C L}(X)\) is the hyperspace of non-empty closed sets, both endowed with the Vietoris topology. The paper contributes to the solution of the following question: Under which conditions is \(\mathcal{K}(X)\) \(C^{*}\)-embedded in \(\mathcal{C L}(X)\)? In the paper the

The subject of hyperspace topologies on closed or closed and compact subsets of a topological space X began in the early part of the last century with the discoveries of Hausdorff metric and Vietoris hit-and-miss topology.

Extension of Hyperspace Selections
In 1951, Ernest Michael wrote a definitive seminal article on hyperspaces raising a general question that became known as the hyperspace selection problem. The present paper contains some aspects of this problem, along with several open questions. Most of these considerations and questions are related to the usual map extension problem, but now in the ...
