A vector field X on the torus \(T^ 2\) is called a Cherry vector field if X has singularities and nontrivial recurrences, the singularities of X are hyperbolic, and X has no closed orbits. In the article Cherry vector fields with exactly two singularities (one sink and one saddle) are considered. The main result of the paper is following: Theorem. If a Cherry vector field on \(T^ 2\) has exactly two singularities, one sink and one saddle, and its divergence at the saddle is less than or equal to zero, then the stable manifold of its sink has full Lebesgue measure on \(T^ 2\).
