## Wedge product

Hi all!

The prof for "theoretical methods in physics" mentioned last week the term "wedge product" but it all remained very unclear to me. I read about it in Wikipedia, but couldnt catch it at all, cause Im doing in the first semester now.

Does anyone know where I could find it well explained?

 itīs was given as a generalisation of the vector product

It's a dot product, but for functions rather than for vectors, it might help if you read upon melnikov analysis, a rather useful tool to analyse bifurcation boundaries on the parameter space, it involves the wedge product in its definition.
 Recognitions: Homework Help Science Advisor read spivak, calculus on manifolds, i think chapter 4. it is a skew symmetric multiplication, used to make determinants more routinely computational. i.e. the determinant of a matrix is essentially the wedge product of its rows. the wedge product of two n vectors, is a vector with n choose 2 entries, namely the 2by2 submatrices of the corresponding 2 by n matrix,..etc.... the wedge product of three n vectors is: guess what? oh there is also a variational version, wherein one takes the wedge product of vector fields and covector fields, etc...

wait what? Is the meaning of wedge product different in melinov analysis as compared to geometry? ... This certainly isnt the meaning in geometry.
