Journal of Inequalities and Applications, 2022 By using a comparison method and some difference inequalities we show that the following higher order difference equation x n + k = 1 f ( x n + k − 1 , … , x n ) , n ∈ N , $$ x_{n+k}=\frac{1}{f(x_{n+k-1},\ldots ,x_{n})},\quad n\in{\mathbb{N}},$$ where k ∈

About a function that allows calculation of all symmetric homogeneous bivariate means [PDF]
Proceedings of the Estonian Academy of Sciences, 2020 In this paper we define a function that allows us to calculate all symmetric homogeneous bivariate means. We also provide examples for this function in case of 17 means.

DONKIN'S DIFFERENTIAL OPERATORS FOR HOMOGENEOUS HARMONIC FUNCTIONS
St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2019 The work continues the study of Donkin operators for homogeneous harmonic functions. Previously, a basic list of such first-order operators for three-dimensional harmonic functions was obtained.

GENERALIZATION OF THE THOMSON FORMULA FOR HOMOGENEOUS HARMONIC FUNCTIONS
St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2019 It is shown that the Thomson formula for three-dimensional harmonic homogeneous functions can be generalized if, instead of purely algebraic linear expressions, one uses a linear algebraic form with the participation of the first order partial ...

Truncated homogeneous symmetric functions [PDF]
Linear and Multilinear Algebra, 2020 Extending the elementary and complete homogeneous symmetric functions, we introduce the truncated homogeneous symmetric function $h_λ^{\dd}$ in $(\ref{THSF})$ for any integer partition $λ$, and show that the transition matrix from $h_λ^{\dd}$ to the power sum symmetric functions $p_λ$ is given by \[M(h^{\dd},p)=M'(p,m)z^{-1}D^{\dd},\] where $D^{\dd ...

Homogeneous Beta-type functions [PDF]
Journal of Classical Analysis, 2017 All beta-type functions, which are p-homogeneous, are determined. Applying this result, we show that a beta-type function is a homogeneous mean iff it is the harmonic one. A reformulation of a result due to Heuvers in terms of a Cauchy difference and the harmonic mean is given.
