AbstractThe classical differential calculus of a higher order is provided by the graded algebra of differential forms on a smooth manifold with the operation of exterior differentiation. Our interest to this notion was motivated by a desire to develop a calculus of differential forms on discrete objects. As a rule, the role of discrete objects is played by discrete sets with additional relation...
