Disorder parameter and canonical quantization approach in lattice gauge   theory
  The work is dedicated to the derivation of the 'functional' integral representation of the disorder parameter. This derivation resolves the problem of the choice of the so called modifed action as well as the problem of the choice of the boundary conditions along the 'time' direction. The question of the gauge fixing in the functional integral representation is also discussed.
