expressions for neutrino wave functions in three cases: with CP violation, without CP violation
and the case when direct e $  transitions are absent,i.e., at (13) = 0 (some
works indicate on this possibility) were obtained. There were also computed transition probabilities
for the case of CP conservation and for absence of direct e $  transitions, i.e.
(13) = 0. It was shown that the probability Pe!e (t) at e $ e neutrino transitions is
definitely positive value if m2
13 = m2
12 + m2

трёхнейтринных смешиваний и осцилляций в общем случае. Вычислены выражения для
волновых функций в трёх случаях: с CP нарушением ( 6= 0), без CP нарушения ( = 0)
и в случае, когда прямые e $  переходы отсутствуют - 
(13) = 0. Также получены
выражения для вероятностей нейтринных переходов (осцилляций) для случая, когда CP
нарушение отсутствует, и в случае, когда прямые e $  переходы отсутствуют. Показано, что требование положительной определённости вероятности переходов Pe!e (t)
при e $ e осцилляциях строго выполняется, если m2 
13 = m2
12 + m2
