Formulas of Variation for a Solution of Neutral Differential Equations with Continuous Initial Condition

Formulas of variation are proved for a solution of quasi-linear controlled neutral differential equations with variable delays, when at the initial moment of time the value of the initial function always coincides with the value of the trajectory.
