Neutrino oscillations and the CPT

The experimental discovery of neutrino mixing is now a well-established fact. Its phenomenological interpretation in the theory of neutrino oscillations gives convincing evidence for a nonzero neutrino mass. Precise measurements of the differences of the neutrino mass squared and mixing angles are in progress. Dedicated experiments to search for CP- and T-odd effects will start soon. At the same time, the consequences of hypothetical CPT violation in the leptonic sector of the Standard Model, in neutrino physics in particular, are being widely discussed. This paper represents a brief review of published articles on the manifestations of CPT violation in the processes of neutrino oscillations and resonant changes of their flavor.
