  • Melnyk, I. (Algebra and Discrete Mathematics, 2007)
    We prove that the set of all Bland preradical filters over an arbitrary differential ring form a quantale with respect to meets where the role of multiplication is played by the usual Gabriel pro-duct of filters. A subset ...
  • Luchko, V.S.; Petravchuk, A.P. (Algebra and Discrete Mathematics, 2007)
    We prove that a Lie nilpotent one-sided ideal of an associative ring R is contained in a Lie solvable two-sided ideal of R. An estimation of derived length of such Lie solvable ideal is obtained depending on the class of ...
  • Laurincikas, A.; Macaitiene, R. (Algebra and Discrete Mathematics, 2007)
    A discrete limit theorem in the sense of weak convergence of probability measures on the complex plane for the Estermann zeta-function is obtained. The explicit form of the limit measure in this theorem is given.
  • Horbachuk, O.; Komarnytskyi, M.; Maturin, Y. (Algebra and Discrete Mathematics, 2007)
    Differential preradicals and differential preradical filters are considered. Differentially closed fields are investigated.
  • Gubareni, N.; Khibina, M. (Algebra and Discrete Mathematics, 2007)
    A ring A is called a piecewise domain with respect to the complete set of idempotents {e1,e2,…,em} if every nonzero homomorphism eiA→ejA is a monomorphism. In this paper we study the rings for which conditions of being ...
  • Fedorenko, V.; Kirichenko, V.; Plakhotnyk, M. (Algebra and Discrete Mathematics, 2007)
    Conjugate classes of continuous maps of the interval [0,1] into itself, whose iterations form a finite group are described. For each of possible groups of iterations one to one correspondence between conjugate classes of ...
  • Dixon, M.R.; Kurdachenko, L.A.; Subbotin, I.Ya. (Algebra and Discrete Mathematics, 2007)
    In the current survey the authors consider some ofthe main theorems concerning groups satisfying certain rank con-ditions. They present these theorems starting with recently estab-lished results. This order of exposition ...
  • Andriychuk, V. (Algebra and Discrete Mathematics, 2007)
    Some properties of R–equivalence and weak approximation in linear algebraic group over global field are generalized to the case of linear algebraic group over an algebraic function field in one variable with pseudofinite ...
  • Al-Sharo, Kh.A.; Shemetkova, O. (Algebra and Discrete Mathematics, 2007)
    With the help of the concept of a generalized central element we study finite groups with the given system of S-quasinormally embedded subgroups.
  • Автор відсутній (Algebra and Discrete Mathematics, 2007)
    This is a special issue of the journal dedicated to the 65th birthday of an outstanding Ukrainian mathematician, one of the founders of our journal Professor Vladimir Kirichenko
  • Chronicle 
    Автор відсутній (Algebra and Discrete Mathematics, 2007)
    The editorial board of the journal “Algebra and Discrete Mathematics” congratulates Yu. S. Samoylenko, Yu. A. Drozd, V. M. Bondarenko, V. V. Lyubashenko, V. L. Ostrovskiy, V. V. Sergeychuk and V. V. Kirichenko with awarding ...
  • 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.
  • Radwan, A.E. (Algebra and Discrete Mathematics, 2007)
    In this paper, we introduce filtered and graded Procesi extensions of filtered and graded rings as a natural modification of Procesi extensions of rings. We show that these extensions behave well from the geometric point of view.
  • Oliynyk, B. (Algebra and Discrete Mathematics, 2007)
    This paper describes a new construction of wreath product of metric spaces. The group of isometries of the wreath product of metric spaces is calculated.
