We discuss the problem of an effective description of the phase transition
phenomena in the pure gluodynamics in SU(2) symmetric QCD. The calculation
method is choosen following the conjecture that the infrared sector of the
theory possesses the same confinement characteristic as the full theory. It is
shown that the analytic description of this phenomena is beyond the Gaussian
method of evaluations of functional integrals. We point to a non-perturbative
method of the evaluation of functional integral for two dimensional Wiener
integral for x4 theory which could solve this problem.
