Length of Vector Tensors

  1. Sep 17, 2009 #1
    Suppose a, b are vectors in R^n, R^m resp. What can I say about the length of [tex]a\otimes b[/tex] wrt a and b?

    You can think of [tex]\otimes[/tex] as the Kronecker product.

    How do you define the "length" of a tensor?

    Euclidean length.
