摘要：

The renormalisation group (RG) method is applied to the investigation of an exactly solvable phase transition model in which only the interaction between fluctuations with equal and antiparallel momenta is taken into account. The RG equation for the model is derived, its exact solution and critical asymptotics are obtained. It is shown that direct calculation of the partition function and solution of the RG equation for the model lead to identical results.
