Functionals, functors and ultrametric spaces
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 ...

On $\ast$-measure monads on the category of ultrametric spaces
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.

Ultrametric spaces and logic programming
Summary: We prove a very general multivalued fixed point theorem for ultrametric spaces which at the same time is a generalization of the multivalued fixed point theorem of Khamsi, Kreinovich and Misane for generalized metric spaces and our (singlevalued) fixed point theorem for ultrametric spaces.

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

Best Proximity Pairs in Ultrametric Spaces [PDF]
In the present paper, we study the existence of best proximity pairs in ultrametric spaces. We show, under suitable assumptions, that the proximinal pair $(A,B)$ has a best proximity pair. As a consequence we generalize a well known best approximation result and we derive some fixed point theorems.

The ultrametrical dynamics for the closed fractal-cluster resource models
The evolution scenario of the resource distribution in the fractal-cluster systems which are identified as organism on Burdakov's classification is suggested.

Random ultrametric trees and applications*
Ultrametric trees are trees whose leaves lie at the same distance from the root. They are used to model the genealogy of a population of particles co-existing at the same point in time.

Some results on ultrametric 2-normed spaces
In this paper, we study the ultrametric 2-normed spaces and the ultrametric 2-Banach spaces. In particular, we establish some results on Cauchy sequences in ultrametric 2-normed spaces.

We present a new conceptual approach for modeling of fluid flows in random porous media based on explicit exploration of the treelike geometry of complex capillary networks.

Ultradiversification of Diversities
In this paper, using the idea of ultrametrization of metric spaces we introduce ultradiversification of diversities. We show that every diversity has an ultradiversification which is the greatest nonexpansive ultra-diversity image of it.
