    A splitting Theorem for FC-hypercentral group G and ZG-module of finite rank is obtained. According to this Theorem, under certain conditions, every extention E of the ZG-module A by the group G is split and all the ...
  • Abelian doppelsemigroups 
    Zhuchok, A.V.; Knauer, K. (Algebra and Discrete Mathematics, 2018)
    A doppelsemigroup is an algebraic system consisting of a set with two binary associative operations satisfying certain identities. Doppelsemigroups are a generalization of semigroups and they have relationships with such ...
  • Aberrations in electromagnetic plasma lenses proposed for intense large-aperture ion beam focusing 
    Butenko, V.I.; Ivanov, B.I. (Вопросы атомной науки и техники, 2003)
    It is shown, that in electromagnetic plasma lenses moment aberrations obey the conservation law of the moment of the ion generalized momentum; they disappear when an ion source is placed in a zero magnetic field. Geometrical ...
