The analytical properties of the amplitudes for the processes (N + K- barY + pi ) and (N + pi -- Y + K) were considered on the basis of the principles of covariance, causality, and spectrality. Kinematic characteristics of these processes were obtained in a frame of reference which is a natural generalization of the Breit system. Dispersion relations were derived forimaginary meson masses. The Vladimirov-Logunov theorem concerning the analyticity of the anti-Hermitian part of the amplitude was extended to the case when all particles involved in the reaction possess different masses. In accordance with the results of previous investigations the region thus obtained contains no physical point. (auth)
