Differential equations has been studied for a long time and its applications are avaliable in many scientific branches. In many years there has been much research activity concerning the oscillaton of delay differential equations. In the first chapter of the thesis, we tread some results given for differential equations in the literature. In the second chapter, general defination and some theorems for oscillations of delay differential equations are given. In the third chapter, oscillation of higher order nonlinear delay differential equations with oscillatory coefficients α(t) x t + r t x(k t ) (n−1) ′ + р(t)F(x(τ(t))) + q(t)G(x(σ(t))) = Φ(t) have been examined. In the fourth chapter, where our original results are given, the higher or...
