Representing the Graviton Self-Energy on de Sitter Background
  We derive a noncovariant but simple representation for the self-energy of a
conformally transformed graviton field on the cosmological patch of de Sitter.
Our representation involves four structure functions, as opposed to the two
that would be necessary for a manifestly de Sitter invariant representation. We
work out what the four structure functions are for the one loop correction due
to a massless, minimally coupled scalar. And we employ the result to work out
what happens to dynamical gravitons.
