The irregular dynamics of the Yang-Mills fields in thermostat

Dynamics of the homogeneous SU (2) Yang-Mills fields in thermostats and at their stochastic quantization are investigated by the Langeven's sources method. It is shown, that with growth of temperature the phase transition confinement-deconfinement in chromodynamics takes place, and quantization of the Yang-Mills fields results in increase of radius of correlation (confinement) colors.
