A case of successful restoration of a tropical wetland evaluated through its Odonata (Insecta) larval assemblage
Wetlands are important wildlife habitats that also provide vital services for human societies. Unfortunately, they have been disappearing due to human activities such as conversion to farmland,Expand

On g-pseudo-contractibility of continua
Abstract Let f and g be maps between topological spaces X and Y. The maps f and g are called pseudo-homotopic provided that there exist a continuum C, points a , b ∈ C and a map H : X × C → Y suchExpand
On representation spaces
Abstract Let C be a class of topological spaces, let P be a subset of C , and let α be a class of mappings having the composition property. Given X ∈ C , we write X ∈ Cl α ( P ) if for every openExpand

Continua with unique symmetric product
Let $X$ be a metric continuum. Let $F_{n}(X)$ denote the hyperspace of nonempty subsets of $X$ with at most $n$ elements. We say that the continuum $X$ has unique hyperspace $F_{n}(X)$ provided thatExpand

The hyperspace HSmn(X) for a finite graph X is unique
Abstract For a metric continuum X and a positive integer n , we consider the hyperspaces C n ( X ) (respectively, F n ( X ) ) of all nonempty closed subsets of X having at most n componentsExpand
Representation space with confluent mappings
Abstract Given a subclass P of the set N of all non-degenerate continua we say X ∈ Cl F ( P ) if for every e > 0 there are a continuum Y ∈ P and a confluent e-map f : X → Y . This closure operator ClExpand
Making Holes in the Hyperspace of Subcontinua of Some Continua
Let be a metric continuum. Let , is said to make a hole in , if is not unico-herent. In this paper, we characterize elements such that makes a hole in , where is either a smooth fan or an ElsaExpand

Making Holes in the Second Symmetric Product of a Cyclicly Connected Graph
A \textit{continuum} is a connected compact metric space. The \textit{second symmetric product} of a continuum $ X $, $ \mathcal{F}_2(X) $, is the hyperspace of all nonempty subsets of $ X $ havingExpand
