In the present paper we construct a family of differential commuting multidimensional operators of order 3, which is closely related to the KdV hierarchy. We find a common eigenfunction of this family and an algebraic relation between these operators. Using these operators we associate a hyperelliptic curve to any solution of stationary KdV equation. A basic generating function of the solution of stationary KdV equation is introduced as special polarization of the hyperelliptic curve equation. The w-function is defined as a unique function with the following property: the second logarithmic derivatives of w are given by the basic generating function of the stationary g-KdV equation solution, in particular, the second logarithmic derivative of w with respect to x gives this solution.
