Query: Absence of radiative corrections in 4-dimensional topological Yang-Mills
  theories   We prove that all connected n-point Green functions of four-dimensional
topological Yang-Mills theories quantized in the (anti-)self-dual Landau gauges
are tree-level exact, i.e. there are no radiative corrections in this gauge
choice.
