Theorem 1 implies that every solution of (1) with one zero is oscilla- tory to the right of this zero and the properties of solutions y without zeros follow from Theorem 2 and
The authors in [ 1 ] studied the existence of periodic solutions of a second order nonlinear difference equation by using the critical point theory for the first time.. The paper [ 5
In conclusion, in the present note, we have obtained an existence and uniqueness result concerning almost automorphic mild solutions for differential equations of the form (1. 1)
In order to apply the upper and lower solutions method to fractional differential equation two-point boundary value problem (1.. 1) complete the proof of the theorem.. We consider
In this paper, we investigate the growth of solutions of complex high order linear differential equations with entire or meromorphic coefficients of finite iterated order and we
In view of the impor- tance of the equation studied in [1], Pachpatte [10, 11, 12] has studied the existence uniqueness and other properties of solutions of more general

The main purpose of this paper is to consider the oscillation theory on meromorphic solutions of second order linear differential equations of the form f ′′ + A(z)f = 0 where A
