Abstract
Using thr renormalization group approach proposed by Millis for the itinera nt electron systems we calculated the specific heat coefficient gamma (T) f or the magnetic fluctuations with susceptibility x(-1) similar to delta (al pha) + \w \ (alpha) + f(q) near the Lifshitz point. The constant value obta ined for alpha = 4/5 and title logarithmic temperature dependence, specific for the non-Fermi behaviour, have been obtained in agreement with the expe rimental data.
