Construction of renormalized collision integral for a quantum gas

A quantum analog is obtained for the renormalized collision integral derived for a classical gas in [1]. As usual [2], considering lag effects in the renormalized collision integral corresponds to taking account of the nondissipative contribution of the interaction.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 8, pp. 107–109, August, 1978.It remains to thank L.
