Composition of entire and analytic functions in the unit ball

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2022
In this paper, we investigate a composition of entire function of several complex variables and analytic function in the unit ball. We modified early known results with conditions providing equivalence of boundedness of $L$-index in a direction for such ...

On Entire Function Solutions to Fermat Delay-Differential Equations

open access: yesAxioms, 2022
This paper concerns the existence and precise expression form of entire solutions to a certain type of delay-differential equation. The significance of our results lie in that we generalize and supplement the related results obtained recently.

Singular values of two-parameter families λ((bz − 1)/z)μ and λ(z/(bz − 1))η

open access: yesJournal of Taibah University for Science, 2017
The singular values of two kinds of two-parameter families of functions (i) fλ,μ(z)=λ((bz−1)/z)μ and fλ,μ(0) = λ(ln b)μ, μ > 0, (ii) gλ,η(z)=λ(z/(bz−1))η and gλ,η(0) = λ/(ln b)η, η > 0; λ∈ℝ∖{0}, z∈ℂ, b > 0, b ≠ 1 are described.

Multiple interpolation with the fast-growing knots in the class of entire functions and its application [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2022
The conditions for the sequence of complex numbers (bn,k) are obtained, such that the interpolation problem g(k-1)(λn) = bn,k, k ∈ 1, s, n ∈ N, where |λk/λk+1| ≤ ∆ < 1, has a unique solution in some classes of entire functions g for which Mg(r) ≤ c1 exp (

On the Zeta-Function of Zeros of Entire Function [PDF]

open access: yesJournal of Siberian Federal University. Mathematics & Physics, 2021
This article is devoted to the study of the properties of the zeta-function of zeros of entire function. We obtained an explicit expression for the kernel of the integral representation of the zetafunction in one ...

On generalized characteristics of smoothness of functions and on average $\nu$-widths in the space $L_2(\mathbb{R})$

open access: yesResearches in Mathematics, 2019
Estimates above and estimates below have been obtained for Kolmogorov, linear and Bernshtein average $\nu$-widths on the classes of functions $W^r (\omega^w, \Psi)$, where $r \in \mathbb{N}$, $\omega^w(f)$ is the generalized characteristic of smoothness ...

Uniqueness of Entire Functions

open access: yesAnnals of the Alexandru Ioan Cuza University - Mathematics, 2011
Uniqueness of Entire Functions In this paper, we study the uniqueness problems on meromorphic functions sharing a finite set. The results extend and improve some theorems obtained earlier by Fang (2002) and Zhang-Lin (2008).

On the zeros of the derivatives of an entire function [PDF]

open access: yesProceedings of the American Mathematical Society, 1957
Let f(z) be an entire function. We define the point set L=Lf on the z-sphere as follows: zo0EL if and only if every neighborhood of zo contains zeros of infinitely many of the functions f(n)(z). In [3] Polya has named this set the final set of f, and collected various facts and conjectures about final sets. The object of this paper is to prove that any
