Thomas precession and spin

With the help of the infinitesimal covariant Lorentz transformations, it is demonstrated that the Bargmann-Michel-Telegdi classical spin equation naturally involves the Thomas precession. The same results are obtained using the alternative phenomenological approach. __________ Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 11, pp. 81–86, November, 2006.
