  • A note on c-normal subgroups of finite groups 
    Skiba, A.N. (Algebra and Discrete Mathematics, 2005)
    Let G be a finite group. We fix in every noncyclic Sylow subgroup P of G some its subgroup D satisfying 1 < |D| < |P| and study the structure of G under assumption that all subgroups H of P with |H| = |D| are c-normal in G.
  • Leonid Shemetkov. His entire life devotion 
    Skiba, A.N.; Monakhov, V.S.; Selkin, M.V.; Vorob’ev, N.T.; Semenchuk, V.N.; Vasil’ev, A.F. (Algebra and Discrete Mathematics, 2013)
    It is given a short scientific biography of Professor L.A. Shemetkov.
  • On Stone sublattices of the lattice of totally local Fitting classes 
    Skiba, A.N.; Vorob’ev, N.N. (Algebra and Discrete Mathematics, 2007)
    Totally local Fitting classes with a Stone lattice of totally local Fitting subclasses are described.
  • On subgroups which cover or avoid chief factors of a finite group 
    Ballester-Bolinches, A.; Ezquerro, L.M.; Skiba, A.N. (Algebra and Discrete Mathematics, 2009)
    A classical topic of research in Finite Group Theory is the following: What is the influence on the structure of the group of the fact that all members of some relevant family of subgoups enjoy a given embedding ...
  • On the F-hypercentre of a finite group 
    Skiba, A.N. (Algebra and Discrete Mathematics, 2012)
    Our main goal here is to give a short survey of some recent results of the theory of the F-hypercentre of finite groups.
  • On well p-embedded subgroups of finite groups 
    Hutsko, N.V.; Skiba, A.N. (Algebra and Discrete Mathematics, 2008)
    Let G be a finite group, H a subgroup of G and HsG the subgroup of H genarated by all those subgroups of H which are s-permutable in G. Then we say that H is well p-embedded in G if G has a quasinormal subgroup T such ...
