This paper deals with the following conditional external problem: find the minimum value of the integral functional   under some boundary conditions and additional constraints   where is some function defined in Banach Space of holomorphic functions in unit disc. It has been shown that the solution of the above problem satisfies the differential equations   and is the Lagrange Multiplier.
