The space of currents arising from rectifiable sets by integrating a differential form is called the space of 2-D rectifiable currents. For a closed bounded rectifiable curve of a number of components in , bounds a rectifiable current of least Area. The theory of rectifiable currents generalizes to -D surfaces in .
