Implication of the bilinear

  1. Jan 3, 2016 #1
    What does it mean that a Killing vector and a total differential of a certain theory are related to bilinears?

    In other words, why would bilinears (e.g. of the forms ##<\gamma_0\epsilon, \gamma_5\gamma_{\mu}\epsilon>## and ##<\gamma_0\epsilon, \gamma_{\mu}\epsilon>## tell us anything about differential forms or killing vectors? Is this their usual usage?

    My question arises from a footnote I read on here in this link where the first is a total differential and the second is Killing vector.
