ANALYTIC FUNCTIONS OF INFINITE ORDER IN HALF-PLANE

open access: yesПроблемы анализа, 2022
J. B. Meles (1979) considered entire functions with zeros restricted to a finite number of rays. In particular, it was proved that if 𝑓 is an entire function of infinite order with zeros restricted to a finite number of rays, then its lower order ...

Methods of extending lower order problems to higher order problems in the context of smallest eigenvalue comparisons

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
The theory of $u_{0}$-positive operators with respect to a cone in a Banach space is applied to the linear differential equations $u^{(4)}+\lambda_{1} p(x)u=0$ and $u^{(4)}+\lambda_{2} q(x)u=0$, $0\leq x\leq 1$, with each satisfying the boundary ...

Hyper Relative Order (p, q) of Entire Functions

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science, 2017
After the works of Lahiri and Banerjee [6] on the idea of relative order (p, q) of entire functions, we introduce in this paper hyper relative order (p, q) of entire functions where p, q are positive integers with p>q and prove sum theorem, product ...

Order and lower order of composite meromorphic functions.

open access: yesMichigan Mathematical Journal, 1989
Let f and g be entire functions, g transcendental. \textit{G. Pólya} [J. Lond. Math. Soc. 1, 12-15 (1926)] proved that if f(g) has finite order, then f has order zero. \textit{F. Gross} [Factorization of meromorphic functions (1972; Zbl 0266.30006)] proved an analogous result for the lower order. \textit{A. Schönhage} [Math. Z.
