Renormalization group evolution of collinear and infrared divergences
  I discuss collinear and infrared divergences in QCD cross sections with massless and massive final-state particles. I present the two-loop renormalization group evolution and resummation in terms of anomalous dimensions, and I show specific results for a variety of QCD hard-scattering processes.
