Noun
two-form (plural two-forms)
(linear algebra) bilinear form
A differential two-form is a sum of the form : Here the basic two-forms measure oriented areas parallel to the coordinate two-planes. Source: Internet
Since ω is a differential two-form, the skew-symmetric condition implies that M has even dimension. Source: Internet
Working with the current two-form and the exterior derivative is usually easier than working with the vector field and divergence, because unlike the divergence, the exterior derivative commutes with a change of (curvilinear) coordinate system. Source: Internet
