Summary: The theory of the Frölicher-Nijenhuis bracket for \(n\)-graded commutative algebras is developed. On the basis of this theory, deformations and recursion operators are defined, both in local and nonlocal cases. New recursion operators are computed for super versions of KdV, NLS, and Boussinesq equations. These operators are shown to generate new series of symmetries for these equations.
