Probability measure monad on the category of ultrametric spaces

open access: yesApplied General Topology, 2008
The set of all probability measures with compact support on an ultrametric space can be endowed with a natural ultrametric. We show that the functor of probability measures with finite supports (respectively compact supports) forms a monad in the ...

Phylogeography and Population Genetics of the Kentucky Endemic Cave Beetle Genus <i>Neaphaenops</i> Jeannel (1920) (Coleoptera: Carabidae: Trechini). [PDF]

open access: yesEcol Evol
This study investigated the evolutionary history and population structure of the genus Neaphaenops, using CO1 gene sequencing from 62 cave populations. The phylogenetic analysis revealed two distinct mega‐populations—northern and southern—separated by the Barren River, leading to the conclusion that the four proposed subspecies are invalid.

Pseudodifferential operators on ultrametric spaces and ultrametric wavelets [PDF]

open access: yesIzvestiya: Mathematics, 2005
A family of orthonormal bases, the ultrametric wavelet bases, is introduced in quadratically integrable complex valued functions spaces for a wide family of ultrametric spaces. A general family of pseudodifferential operators, acting on complex valued functions on these ultrametric spaces is introduced.

Functionals, functors and ultrametric spaces

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2014
We consider different classes of functionals defined on the set of continuous functions on ultrametric spaces. Similarly as in the case of probability measures, idempotent measures, max-min measures and upper semicontinuous capacities we endow the sets ...

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2022
The functor of $\ast$-measures of compact support on the category of ultrametric spaces and non-expanding maps is introduced in the previous publication of the authors.

Trees and ultrametric Möbius structures [PDF]

open access: yes, 2017
We define the concept of an ultrametric Möbius space (Z,M) and show that the boundary at infinity of a nonelementary geodesically complete tree is naturally an ultrametric Möbius space.

A Note on Ultrametric Spaces, Minimum Spanning Trees and the Topological Distance Algorithm

open access: yesInformation, 2020
We relate the definition of an ultrametric space to the topological distance algorithm—an algorithm defined in the context of peer-to-peer network applications.

Coronas of ultrametric spaces [PDF]

open access: yes, 2007
summary:We show that, under CH, the corona of a countable ultrametric space is homeomorphic to $\omega^*$. As a corollary, we get the same statements for the Higson's corona of a proper ultrametric space and the space of ends of a countable locally ...
