Abstract
This article presents sufficient conditions for the uniform stability of the zero solution when p equals zero, the uniform boundedness and uniform ultimate boundedness of all solutions in case p does not equal zero of the third-order nonlinear delay differential equation (1). By constructing Lyapunov functionals we achieved new contribution which includes and improves some related results existing in the relevant literature.

Keywords: Lyapunov functional, Stability, Boundedness, Third-order delay differential equations.
