Abstract. In the present note we characterize the four-dimensional Riemannian manifolds for which any skew-symmetric Stanilov operator with respect to any plane in the tangent space to the manifold commute with the corresponding generalized Jacobi operator, at any point of the manifold. These classes of manifolds Gilkey called Stanilov-Videv manifolds.
