Abstract: Consider the delay differential equation
\dot x(t)=g(x(t),x(t-r)),\tag1
where $r>0$ is a constant and $g \br^2\rightarrow\br$ is Lipschitzian. It is shown that if $r$ is small, then the solutions of (1) have the same convergence properties as the solutions of the ordinary differential equation obtained from (1) by ignoring the delay.

Keywords: delay differential equation, equilibrium, convergence
