Abstract:
Exactly solvable model is studied which shows the phase transition taking into
account only interaction between fluctuations with equal and oppositely directed momenta.
Critical and tricritical behaviour influence of frozen-in impurities on the phase
transition is studied and it is shown that in the narrow region proportional to the
impurity concentration the phase transition is smeared.
