The Oscillation on Solutions of Some Classes of Linear Differential Equations with Meromorphic Coefficients of Finite [p,q]-Order

الملخص EN

This paper considers the oscillation onmeromorphic solutions of the second-order linear differential equationswith the form f′′+A(z)f=0, where A(z) is a meromorphic functionwith [p,q]-order.

We obtain some theorems which are the improvementand generalization of the results given by Bank and Laine, Cao andLi, Kinnunen, and others.
