  • 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 ...
  • On τ-closed totally saturated group formations with Boolean sublattices 
    Safonov, V.G. (Algebra and Discrete Mathematics, 2008)
    In the universe of finite groups the description of τ-closed totally saturated formations with Boolean sublattices of τ-closed totally saturated subformations is obtained. Thus, we give a solution of Question 4.3.16 proposed ...
  • Planar trees, free nonassociative algebras, invariants, and elliptic integrals 
    Drensky, V.; Holtkamp, R. (Algebra and Discrete Mathematics, 2008)
    We consider absolutely free algebras with (maybe infinitely) many multilinear operations. Such multioperator algebras were introduced by Kurosh in 1960. Multioperator algebras satisfy the Nielsen-Schreier property and ...
  • Random walks on finite groups converging after finite number of steps 
    Vyshnevetskiy, A.L.; Zhmud, E.M. (Algebra and Discrete Mathematics, 2008)
    Let P be a probability on a finite group G, P(n)=P∗…∗P (n times) be an n-fold convolution of P. If n→∞, then under mild conditions P(n) converges to the uniform probability U(g)=1|G| (g∈G). We study the case when the ...
  • The free spectra of varieties generated by idempotent semigroups 
    Pluhar, G.; Wood, J. (Algebra and Discrete Mathematics, 2008)
    We give an exact formula for the logarithm of the free spectra of band varieties.
