ABSTRACT
This paper deals with a certain third-order non-linear differential equation with multiple deviating arguments. Some sufficient conditions are set up for all solutions and their derivatives to be uniformly bounded.
Keywords and Phrases: Non-linear differential equation; third order; multiple deviating arguments; bounded solutions.
RESUMEN
