Oscillation of arbitrary-order derivatives of solutions to linear differential equations taking small functions in the unit disc

Electronic Journal of Differential Equations, 2015
In this article, we study the relationship between solutions and their derivatives of the differential equation $$ f''+A(z)f'+B(z)f=F(z), $$ where $A(z), B(z), F(z)$ are meromorphic functions of finite iterated p-order in the unit disc.

Exponent of convergence of solutions to linear differential equations in the unit disc

Electronic Journal of Differential Equations, 2015
In this article, we study the exponent of convergence of $f^{(i) }-\varphi $ where $f\not\equiv 0$ is a solution of linear differential equations with analytic and meromorphic coefficients in the unit disc and $\varphi $ is a small function of $f ...

Meromorphic solutions to non-linear differential-difference equations

Electronic Journal of Differential Equations, 2018
We consider the non-linear differential-difference equation $$ c(z)w(z+1)+a(z)\frac{w'(z)}{w(z)}=R(z,w(z)), $$ where R(z,w(z)) is rational in w(z) with rational coefficients, a(z) and c(z) are non-zero rational functions.
