CRITICAL-BEHAVIOR OF THE RANDOM POTTS-MODEL

The phase transition in the continual random n-component Potts model i s studied by the renormalization group method. It is shown that for th e three-dimensional model and n=3 the phase transition is to be of the first order. In the case n=2 which corresponds to the random Ising mo del the stable fixed point exists as early as in the one-loop approxim ation of renormalization group equations.
