The Myers-Steenrod theorem for Finsler manifolds of low regularity

open access: yes, 2016
We prove a version of Myers-Steenrod's theorem for Finsler manifolds under minimal regularity hypothesis. In particular we show that an isometry between $C^{k,\alpha}$-smooth (or partially smooth) Finsler metrics, with $k+\alpha>0$, $k\in \mathbb{N} \cup

Twisted immanant and matrices with anticommuting entries

open access: yes, 2015
This article gives a new matrix function named "twisted immanant," which can be regarded as an analogue of the immanant. This is defined for each self-conjugate partition through a "twisted" analogue of the irreducible character of the symmetric group ...

Generating matrix of the bi-periodic Lucas numbers

open access: yes, 2016
In this paper, firstly, we introduce the Q_{l}-Generating matrix for the bi-periodic Lucas numbers. Then, by taking into account this matrix representation, we obtain some properties for the bi-periodic Fibonacci and Lucas ...

A Historical Analysis of The Padovan Sequence

open access: yesInternational Journal of Trends in Mathematics Education Research, 2020
In the present text, we present some possibilities to formalize the mathematical content and a historical context, referring to a numerical sequence of linear and recurrent form, known as Sequence of Padovan or Cordonnier.

Predicting the overall survival of patients with chronic lymphocytic leukemia in the dynamics of the disease

open access: yesКачественная клиническая практика, 2023
Relevance. The high prevalence of chronic lymphocytic leukemia (CLL) in elderly and senile patients of the European population dictates the need to find a publicly available solution to the problem of prognosis in this cohort of patients.

On Pfaffian random point fields

open access: yes, 2013
We study Pfaffian random point fields by using the Moore-Dyson quaternion determinants. First, we give sufficient conditions that ensure that a self-dual quaternion kernel defines a valid random point field, and then we prove a CLT for Pfaffian point ...

Higher-Order Jacobsthal–Lucas Quaternions

open access: yesAxioms, 2022
In this work, we define higher-order Jacobsthal–Lucas quaternions with the help of higher-order Jacobsthal–Lucas numbers. We examine some identities of higher-order Jacobsthal–Lucas quaternions. We introduce their basic definitions and properties.

Binomial Transform for Quadra Fibona-Pell Sequence and Quadra Fibona-Pell Quaternion

open access: yesUniversal Journal of Mathematics and Applications, 2022
The main object of the study is to consider the binomial transform for quadra Fibona-Pell sequence and quadra Fibona-Pell quaternion. In the paper, which consists of two parts in terms of the results found, the first step was taken for the sequence by ...
