Applied General Topology, 2003 We prove that the hyperspace of closed bounded sets with the Hausdor_ topology, over an almost convex metric space, is an absolute retract. Dense subspaces of normed linear spaces are examples of, not necessarily connected, almost convex metric spaces ...

Permafrost Distribution in the Canadian Rockies: Key Variables Influencing Patch‐Scale Variability
Permafrost and Periglacial Processes, Volume 37, Issue 3, Page 372-390, July/September 2026.ABSTRACT The spatial distribution of permafrost in mountainous regions is influenced by various factors such as topography, climate, vegetation, and substrate. Despite the existence of comprehensive permafrost maps at national and global levels, they fail to accurately represent the patch‐scale (e.g., < 25 m) permafrost distribution in characteristic ...

Local Connectedness in Hyperspaces
Rocky Mountain Journal of Mathematics, 2006 \textit{W. Makuchowski} [Bull. Pol. Acad. Sci., Math. 47, No. 2, 119--126 (1999; Zbl 0929.54012)] has proved that if \(X\) is a Hausdorff compact space, then local connectedness and local arcwise connectedness of the hyperspace \(C(X)\) of all subcontinua of \(X\) and of the hyperspace \(2^X\) of all non-empty closed subsets of \(X\) are equivalent at ...

Environmental Microbiology, Volume 28, Issue 7, July 2026.Xanthoria parietina associates with an unexpectedly high diversity of Trebouxia phycobionts within clade A across the Mediterranean Basin. Climatic niche modelling reveals that differences in photobiont climatic preferences contribute to symbiont switching and help explain the broad ecological amplitude and geographic success of this widespread lichen.

Sobre los continuos tipo θ y θn
Revista Integración, 2015 En 1974 el Profesor R. W. FitzGerald definió los continuos tipo θ y θn. (Un continuo X es un continuo tipo θ (tipo θn, para algún número natural n) si para cada subcontinuo K de X, resulta que X \ K sólo tiene un número finito de componentes (X \ K ...

Some remarks on hyperspaces [PDF]
Proceedings of the American Mathematical Society, 1969 1. The purpose of this paper is to answer a question of R. Schori [3] and to provide simpler arguments for some generalizations of Schori's results. If X is a metric space, the hyperspace of X, denoted 2X, is the space of all nonvoid closed subsets of X with the usual Hausdorff metric.
