Revision comment (for changes between this and next version):

Expand and clarify entry. Add a more formal definition.

Content:

A {\em skew-symmetric} (or {\em antisymmetric}) {\em bilinear form} is a bilinear form $B$ which is skew-symmetric in the two coordinates; that is, $B(x,y) = -B(y,x)$ for all vectors $x$ and $y$. In particular, this means that $B(x,x)=0$.

A bilinear form is skew-symmetric iff its defining matrix is skew-symmetric.
