Аннотация:
Развитый ранее метод, основанный на континуальном интеграле, применяется
для определения гидродинамического гамильтониана неидеального
бозе-газа и построения теории возмущений, свободной от расходимостей при малых энергиях и импульсах. Рассмотрены кинетические уравнения
при низких температурах. Вычислен в квадратурах коэффициент
первой вязкости.
