vertices in the path integral formalism The origin of the ln det G item (where G(\phi) is the Green function in the \lambda \phi^4 model, for instance)? Sincerelly, Leonid.

QCD, FP ghosts Why (Faddeev-Popov) ghosts are absent in the axial gauge A_3=0? Sincerelly, Leonid.

Garmonic potential Can the "garmonic" ("squared") potential V\sim r^2 supply the correct infrared behaviour necessary for confinement (i.e. the q^(-\alpha), \alpha>0 as q\to 0 in the momentum space)? Leonid.

Which is the connection between the perimeter law for Wilson loops and quantum fluctuations of matter fields (presenting in the QCD Lagrangian); and why quantum fluctuations of gauge (Yang-Mills, gluonic) fields infolve the area law for appropriate Wilson loops? Senk You. Leonid.

Why a magnetic current obviously must be C- parity odd in the (exact) SU(2) theory? (C^{-1} J_M C=-J_M). Best regard. Leonid
