  • Representations of linear groups over Ā₂-algebras 
    Timoshin, A.S. (Algebra and Discrete Mathematics, 2004)
    In the space of irreducible unitary representations of a linear group over an algebra of type Ā₂ an open dense subset of representations in the general position is singled out. This set is identified, up to simple ...
  • Root vectors of the composition algebra of the Kronecker algebra 
    Chen, X. (Algebra and Discrete Mathematics, 2004)
    According to the canonical isomorphism between the positive part Uq⁺(g) of the Drinfeld–Jimbo quantum group Uq(g) and the generic composition algebra C(∆) of Λ, where the Kac–Moody Lie algebra g and the finite ...
  • Some applications of Hasse principle for pseudoglobal fields 
    Andriychuk, V. (Algebra and Discrete Mathematics, 2004)
    Some corollaries of the Hasse principle for Brauer group of a pseudoglobal field are obtained. In particular we prove Hasse-Minkowski theorem on quadratic forms over pseudoglobal field and the Hasse principle for quadratic ...
  • Subsets of defect 3 in elementary Abelian 2-groups 
    Novikov, B.V.; Polyakova, L.Yu. (Algebra and Discrete Mathematics, 2004)
  • Torsion-free groups with every proper homomorphic image an N₁-group 
    Ercan, S. (Algebra and Discrete Mathematics, 2004)
    In this article it is proved that a torsion-free locally nilpotent groups with non-trivial Fitting subgroup and every proper homomorphic image an N₁-group is an N₁-group(and so it is nilpotent).
  • Two-step tilting for standardly stratified algebras 
    Frisk, A. (Algebra and Discrete Mathematics, 2004)
    We study the class of standardly stratified algebras introduced by Cline, Parshall and Scott, and its subclass of the so-called weakly properly stratified algebras, which generalizes the class of properly stratified ...
  • Unitarizable and non-unitarizable represenations of algebras generated by idempotents 
    Popovych, S.; Turowska, L. (Algebra and Discrete Mathematics, 2004)
    The problem of unitarization of representations of algebras generated by idempotents with linear relations is studied. Construction of non-unitarizable representations for some subintervals of continuous spectrum is ...
