How to get the normal bivector to a surface??
Given a surface [tex]f(x)=0[/tex] in a manifold, for examle [tex]R^n[/tex], its normal vector can be constructed as [tex]{\partial}^{\mu}f[/tex].
But i don't know how to construct the so-called normal bivector (or binormal) to this surface. It has the form as [tex]{\epsilon}_{\mu \nu}[/tex]...
