Diagrammatic Notation

  1. Apr 10, 2008 #1
    Hi guys

    I was first introduced to diagrammatic notation in Roger Penrose's book "Road to Reality".
    I wanted to know if any of you are familiar with diagrammatic notation for tensors? As such, is it worthwhile learning? Its certainly alot clearer (for me anyway :P) than index notation for some of the more complicated structures.

    I quite like the way contraction looks and a few of the graphical 'proofs' seem very natural (like the determinant of a product being the product of the determinants).

    As an aside: If you were to add two tensors of the same valence, what would the new structure look like?

    It's junk, in my opinion.
