Abstract

It is shown, real crystals with phase transition the thermal conductivity coefficient k?,?(T) may be present by correlation function current — current. The last one is described by the transport Bethe-Salpeter type equation and in self-ñîrrelated motion of phonons approximation the behavior of systems near Tc is described by the system of two re normalization group equations for the vertex U and the phonon frequencies ?. It is calculation of the values of critical indexes for the ferroelectric crystals. It is shown that this indexes are connected with the dynamical index of crystal.
