    AnnotationThe classical Poincar´e weak recurrence theorem states that for any probability space (Ω, S, P), any P-measure preserving transformation T, and any A ∈ S, almost all points of A return to A. In the present paper the Poincar´e theorem is proved when the σ-algebra S is replaced by any σ-complete MV-algebra

    AnnotationThe production of negative strangeness in reactions of inelastic antineutrino scattering on a nucleus provides information on the modification of strange degrees of freedom in nuclear matter. We calculate cross sections of the reaction channels <(nu)over bar>(e(mu)) --> e(+) (mu(+)) + K- and <(nu)over bar>(e(mu)) + p --> Lambda + e(+) (mu(+)) and investigate their sensitivity to the medium effects. In particular, we consider effects induced by the presence of a low-energy excitation mode in the K-spectrum, associated with correlated Lambda-particle and proton-hole states, and by renormalization of the weak interaction in medium. In order to avoid double counting, various contributions to antineutrino scattering are classified with the help of the optical theorem, formulated within the nonequilibrium Green's function technique.
