Modular Locally Constant Mappings in Vector Ultrametric Spaces [PDF]

Abstract and Applied Analysis, 2011
We give some sufficient conditions for mappings defined on vector ultrametric spaces to be modular locally constant.

Ultrametrically injective spaces [PDF]

Proceedings of the American Mathematical Society, 1987
We study the injective objects in the category of ultrametric spaces with contractive mappings. As a result, the property of spherical completeness is characterized in several new ways related to extensions of uniformly continuous mappings and to extensions of isometries. A construction of the injective envelope is also given.

CUDA and OpenMp Implementation of Boolean Matrix Product with Applications in Visual SLAM

Algorithms, 2023
In this paper, the concept of ultrametric structure is intertwined with the SLAM procedure. A set of pre-existing transformations has been used to create a new simultaneous localization and mapping (SLAM) algorithm.

ROUNDNESS PROPERTIES OF ULTRAMETRIC SPACES [PDF]

Glasgow Mathematical Journal, 2013
AbstractMotivated by a classical theorem of Schoenberg, we prove that an n + 1 point finite metric space has strict 2-negative type if and only if it can be isometrically embedded in the Euclidean space $\mathbb{R}^{n}$ of dimension n but it cannot be isometrically embedded in any Euclidean space $\mathbb{R}^{r}$ of dimension r < n.

Homogeneous Ultrametric Spaces

Journal of Algebra, 1996
Fortsetzung von zwei vorangehenden Arbeiten über verallgemeinerte ultrametrische Räume [the authors, Generalized ultrametric spaces I, Abh. Math. Semin. Univ. Hamb. 66, 55-73 (1996); and Part II (1997)]. Es wird der Begriff des homogenen ultrametrischen Raumes eingeführt [the authors, C. R. Math. Acad. Sci., Soc. R. Can. 18, 1-16 (1996; Zbl 0853.54029)]

Bounded distortion homeomorphisms on ultrametric spaces [PDF]

, 2010
It is well-known that quasi-isometrics between R-trees induce power quasi-symmetric homeomorphisms between their ultrametric end spaces. This paper investigates power quasi-symmetric homeomorphisms between bounded, complete, uniformly perfect ...

Pseudodifferential operators on ultrametric spaces and ultrametric wavelets [PDF]

Izvestiya: 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.
