  • There isn’t much duality in radical theory 
    Gardner, B.J. (Algebra and Discrete Mathematics, 2007)
    The definitions of radical and semi-simple classes are in a natural sense dual to each other. However, statements dual in the same sense to theorems of radical theory tend to be false. Some insights may nevertheless be ...
  • Groups whose non-normal subgroups have small commutator subgroup 
    De Falco, M.; de Giovanni, F.; Musella, C. (Algebra and Discrete Mathematics, 2007)
    The structure of groups whose non-normal subgroups have a finite commutator subgroup is investigated. In particular, it is proved that if k is a positive integer and G is a locally graded group in which every non-normal ...
  • On sum of a nilpotent and an ideally finitealgebras 
    Bilun, S.V. (Algebra and Discrete Mathematics, 2007)
    We study associative algebras R over arbitrary fields which can be decomposed into a sum R=A+B of their subalgebras A and B such that A²=0 and B is ideally finite (is a sum of its finite dimensional ideals). We prove that ...
  • Mathematics competition 
    Автор відсутній (Algebra and Discrete Mathematics, 2007)
    The Shevchenko Scientific Society of America and U.S.-Ukraine Foundation are sponsoring an annual mathematics competition for young mathematicians in Ukraine. The winner of the competition will be awarded a prize of ...
  • Information on the conference ASADE-2007 
    Автор відсутній (Algebra and Discrete Mathematics, 2007)
    The international conference “Algebraic systems and their applications in differential equations and other domains of mathematics” took place in Chisinau (Republic of Moldova) from 21-st to 23-rd of August 2007. It was ...
  • Hereditary stable tubes in module categories 
    Simson, D.; Skowronski, A. (Algebra and Discrete Mathematics, 2007)
    The concepts of a self-hereditary stable tube T and a hereditary stable tube T in a module category modA are introduced, where A is a finite dimensional algebra over an algebraically closed field. Characterisations ...
  • Multi-solid varieties and Mh-transducers 
    Shtrakov, S. (Algebra and Discrete Mathematics, 2007)
    We consider the concepts of colored terms and multi-hypersubstitutions. If t∈Wτ(X) is a term of type τ, then any mapping αt:PosF(t)→N of the non-variable positions of a term into the set of natural numbers is called a ...
  • On semisimple algebra codes: generator theory 
    Martınez-Moro, E. (Algebra and Discrete Mathematics, 2007)
    The class of affine variety codes is defined as the Fq linear subspaces of A a Fq-semisimple algebra, where Fq is the finite field with q=pr elements and characteristic p. It seems natural to impose to the code some extra ...
  • Distribution of arithmetical functions on some subsets of integers 
    Katai, I. (Algebra and Discrete Mathematics, 2007)
    This is a survey paper on the distribution of arithmetical functions on some subsets of integers. Continuous homomorphisms as arithmetical functions, and sets of uniqueness are also treated.
  • F–semigroups 
    Giraldes, E.; Marques-Smith, P.; Mitsch, H. (Algebra and Discrete Mathematics, 2007)
    A semigroup S is called F- semigroup if there exists a group-congruence ρ on S such that every ρ-class contains a greatest element with respect to the natural partial order ≤S of S (see [8]). This generalizes the concept ...
  • Nonstandard additively finite triangulated categories of Calabi-Yau dimension one in characteristic 3 
    Bialkowski, J.; Skowronski, A. (Algebra and Discrete Mathematics, 2007)
    We prove that there exist nonstandard K-linear triangulated categories with finitely many indecomposable objects and Calabi-Yau dimension one over an arbitrary algebraically closed field K of characteristic 3, using deformed ...
  • Commutative reduced filial rings 
    Andruszkiewicz, R.R.; Sobolewska, M. (Algebra and Discrete Mathematics, 2007)
    A ring R is filial when for every I, J, if I is an ideal of J and J is an ideal of R then I is an ideal of R. Several characterizations and results on structure of commutative reduced filial rings are obtained.
  • Open problems in Radical theory (ICOR-2006) 
    Gardner, B.J.; Krempa, Jan; Wiegandt, R. (Algebra and Discrete Mathematics, 2007)
  • History of the conferences on Radical Theory 
    Márki, L.; Wiegand, R. (Algebra and Discrete Mathematics, 2007)
  • The international conference on radicals ICOR-2006 
    Bezushchak, O.; Kirichenko, V. (Algebra and Discrete Mathematics, 2007)
    The regular International Conference on Radicals (ICOR-2006) was held from July 30 till August 5, 2006, in Kyiv, Ukraine. The conference was organized by Kyiv National Taras Shevchenko University and Institute of ...
