euler type half Linear Differential Equation with periodic coefficients
Abstract and Applied Analysis, 2013Co-Authors: Ondřej Došlý, Hana FunkovaAbstract:We investigate oscillatory properties of the perturbed half-Linear Euler Differential Equation. We show that the results of the recent paper by O. Doslý and H. Funkova (2012) remain to hold when constants in perturbation terms are replaced by periodic functions.

Archivum Mathematicum, 2017Co-Authors: Ondřej DoslýAbstract:We establish an asymptotic formula for a pair of Linearly independent solutions of the subcritical Riemann–Weber type half-Linear Differential Equation. We also complement the results of the author and M. Unal, Acta Math. Hungar. 120 (2008), 147–163, where the Equation was considered in the critical case.

half Linear oscillation criteria perturbation in term involving derivative
Nonlinear Analysis-theory Methods & Applications, 2010Co-Authors: Ondřej Doslý, Simona FisnarovaAbstract:Abstract We consider the nonoscillatory half-Linear Differential Equation ( r ( t ) Φ ( x ′ ) ) ′ + c ( t ) Φ ( x ) = 0 , Φ ( x ) ≔ | x | p − 2 x , p > 1 , and we study oscillatory properties of its perturbation (∗ ) [ ( r ( t ) + r ( t ) ) Φ ( x ′ ) ] ′ + ( c ( t ) + c ( t ) ) Φ ( x ) = 0 . We use the Riccati technique and relationship between (∗) and a certain associated Linear Equation. The results are applied to the perturbed Euler-type Equation.

Infinite order Linear Differential Equation satisfied by $p$-adic Hurwitz-type Euler zeta functions
2021Co-Authors: Kim Min-sooAbstract:In 1900, at the international congress of mathematicians, Hilbert claimed that the Riemann zeta function $\zeta(s)$ is not the solution of any algebraic ordinary Differential Equations on its region of analyticity. In 2015, Van Gorder considered the question of whether $\zeta(s)$ satisfies a non-algebraic Differential Equation and showed that it formally satisfies an infinite order Linear Differential Equation. Recently, Prado and Klinger-Logan extended Van Gorder's result to show that the Hurwitz zeta function $\zeta(s,a)$ is also formally satisfies a similar Differential Equation \begin{Equation*}\label{HurDE} T\left[\zeta (s,a) - \frac{1}{a^s}\right] = \frac{1}{(s-1)a^{s-1}}. \end{Equation*} But unfortunately in the same paper they proved that the operator $T$ applied to Hurwitz zeta function $\zeta(s,a)$ does not converge at any point in the complex plane $\mathbb{C}$. In this paper, by defining $T_{p}^{a}$, a $p$-adic analogue of Van Gorder's operator $T,$ we establish an analogue of Prado and Klinger-Logan's Differential Equation satisfied by $\zeta_{p,E}(s,a)$ which is the $p$-adic analogue of the Hurwitz-type Euler zeta functions \begin{Equation*}\label{HEZ} \zeta_E(s,a)=\sum_{n=0}^\infty\frac{(-1)^n}{(n+a)^s}. \end{Equation*} In contrast with the complex case, due to the non-archimedean property, the operator $T_{p}^{a}$ applied to the $p$-adic Hurwitz-type Euler zeta function $\zeta_{p,E}(s,a)$ is convergent $p$-adically in the area of $s\in\mathbb{Z}_{p}$ with $s\neq 1$ and $a\in K$ with $|a|_{p}>1,$ where $K$ is any finite extension of $\mathbb{Q}_{p}$ with ramification index over $\mathbb{Q}_{p}$ less than $p-1.$Comment: 18 pages.

perturbations of the half Linear euler Differential Equation
Results in Mathematics, 2000Co-Authors: A Elbert, Albert SchneiderAbstract:Oscillation/nonoscillation properties of the perturbed half-Linear Euler Differential Equation in the critical case are investigated. Strong connections are found between these half-Linear Differential Equations and some Linear Differential Equations, whose coefficient is the perturbation itself. In addition if the solutions of the corresponding Linear Differential Equation satisfy two integral inequalities, then the asymptotic form of the solutions of the half-Linear Differential Equation is established. Examples are given for the latter case.
