Oscillatory behaviour of Solutions for First Order Delay Differential Equations with Monotone Arguments

This study investigates the oscillation criteria for solutions of first order delay differential equations with monotone argument the condition for oscillation of DDEs with monotone argument the established. We employed the method of Chatzarakis and Li to improve the first order DDEs to monotone argument. The result obtained demonstrate that the oscillation of first order first order delay is also oscillatory when the value of is large enough. Therefore, it is recommended for further modification on our criteria so that it can accommodate higher order delay.
