Wedge product in tensor notation

  1. Apr 30, 2012 #1
    Is the following the definition of wedge product in tensor notation?

    Let [tex] A \equiv A_i [/tex] be a matrix one form. Then

    A \wedge A \wedge A \wedge A \wedge A = \epsilon^{abcde}A_a A_b A_c A_d A_e


    in 5 dimensions. This question is in reference to the winding number of maps.

    You should write
    A \equiv A_i dx^i

    i.e. the wedge product is defined on the basis. Then your wedge product has as components

    A_{[a}A_b A_c A_d A_{e]}
