Geometric and extern product

  1. May 1, 2005 #1
    Dear friends,

    I'm trying to find a resolution of the three vectors product in geometrical algebra, and there's no book or text that explaines this.

    The geometrical product of two vectors is defined like this:


    Where a·b is the inner product, and a^b is the outer product.

    a·b = 1/2 (ab+ba) and a^b=1/2 (ab-ba)

    In the case of three vectors, I have:


    where a^b^c is the external product of three vectors.

    But the question is how to calculate abc. Does anybody knows it???
