A two-form can be integrated over an oriented surface, and the resulting integral is equivalent to the surface integral giving the flux of + +. Unlike the cross product, and the three-dimensional vector calculus, the wedge product and the calculus of differential forms makes sense in arbitrary dimension and on more general manifolds (curves ...
