Sažetak
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.
