Abstract
Variation formulas of solution are proved for a non-linear differential equation with constant delay. In this paper, the essential novelty is the effect of delay perturbation in the variation formulas. The continuity of the initial condition means that the values of the initial function and the trajectory always coincide at the initial moment.
Keywords.: Delay differential equation; variation formula of solution; effect of delay perturbation; continuous initial condition
