The 3D Yang-Mills system. Lecture notes on the Karabali-Nair theory
  The Schroedinger functional treatment of 2+1 D Yang-Mills theory is recapitulated, in great calculational detail, by following three papers of Karabali, Kim and Nair in 1998/99. The notes include the Hermitean WZW model, regularization, the functional Hamiltonian, the string tension and the magnetic mass problem of 4D hot gluons.
