Computation of Nevanlinna characteristic functions derived from generating functions of some special numbers [PDF]

open access: yesJournal of Inequalities and Applications, 2018
In the present paper, firstly we find a number of poles of generating functions of Bernoulli numbers and associated Euler numbers, denoted by n(a,B) $n ( a,\mathbf{B} ) $ and n(a,E) $n ( a,E ) $, respectively.

On the relation between the Lebesgue integral means and Nevanlinna characteristic of analytic functions in the unit disc [PDF]

open access: yesМатематичні Студії, 2011
The best possible asymptotic estimates for Lebesgue integral means $m_{p}(r,log f), 1 leq p$ of logarithms of analytic functions $f(z)$ in the unit disc in terms of their Nevanlinna characteristic $T(r,f)$ are obtained.

The Nevanlinna characteristic and maximum modulus of entire functions of finite order with random zeros (in Ukrainian) [PDF]

open access: yesМатематичні Студії, 2011
Let (r_n) be a positive nondecreasing sequence of finite genus tending to +∞ , and (η_n(ω)) be a sequence of independent random variables such that η_n(ω) are uniformly distributed on the circles |z|=r_n. Then for almost all ω the following assertion

Characteristic estimation of differential polynomials

open access: yesJournal of Inequalities and Applications, 2021
In this paper, we give the characteristic estimation of a meromorphic function f with the differential polynomials f l ( f ( k ) ) n $f^{l}(f^{(k)})^{n}$ and obtain that T ( r , f ) ≤ M N ‾ ( r , 1 f l ( f ( k ) ) n − a ) + S ( r , f ) $$\begin{aligned ...

A note on the value distribution of $\phi f^2 f^{(k)}-1$

open access: yesМатематичні Студії, 2021
In this paper, we study the value distribution of the differential polynomial $\varphi f^2f^{(k)}-1$, where $f(z)$ is a transcendental meromorphic function, $\varphi (z)\;(\not\equiv 0)$ is a small function of $f(z)$ and $k\;(\geq 2)$ is a positive ...

A growth property of the Nevanlinna characteristic [PDF]

open access: yesProceedings of the American Mathematical Society, 1970
We prove here a relation between the rate of growth of the Nevanlinna characteristic of a meromorphic function f ( z ) f(z) , the size of a deficient value τ \tau , and the sets where f ( z ) f(z) is close to τ \tau .
