On the oscillation of certain second-order linear differential equations

Yueyang Zhang

This paper consists of three parts: First, letting $b_{1} (z)$ , $b_{2} (z)$ , $p_{1} (z)$ and $p_{2} (z)$ be nonzero polynomials such that $p_{1} (z)$ and $p_{2} (z)$ have the same degree $k \geq 1$ a…

A Malmquist--Steinmetz theorem for difference equations

Yueyang Zhang, Risto Korhonen

It is shown that if the equation \begin{equation*} f(z+1)^n=R(z,f), \end{equation*} where $R (z, f)$ is rational in both arguments and $°_{f} (R (z, f)) \neq = n$ , has a transcendental merom…
