  • Finitely presented quadratic algebras of intermediate growth 
    Koçak, D. (Algebra and Discrete Mathematics, 2015)
    In this article, we give two examples of finitely presented quadratic algebras (algebras presented by quadratic relations) of intermediate growth.
  • Lattice groups 
    Kurdachenko, L.A.; Yashchuk, V.S.; Subbotin, I.Ya. (Algebra and Discrete Mathematics, 2015)
    In this paper, we introduce some algebraic struc-ture associated with groups and lattices. This structure is a semi-group and it appeared as the result of our new approach to thefuzzy groups andL-fuzzy groups whereLis a ...
  • Lie and Jordan structures of differentially semiprime rings 
    Artemovych, O.D.; Lukashenko, M.P. (Algebra and Discrete Mathematics, 2015)
    Properties of Lie and Jordan rings (denoted respectively by RL and RJ) associated with an associative ring R are discussed. Results on connections between the differentially simplicity (respectively primeness, semiprimeness) ...
  • New families of Jacobsthal and Jacobsthal-Lucas numbers 
    Catarino, P.; Vasco, P.; Campos, H.; Aires, A.P.; Borges, A. (Algebra and Discrete Mathematics, 2015)
    In this paper we present new families of sequences that generalize the Jacobsthal and the Jacobsthal-Lucas numbers and establish some identities. We also give a generating function for a particular case of the sequences presented.
  • On algebraic graph theory and non-bijectivemultivariate maps in cryptography 
    Ustimenko, V. (Algebra and Discrete Mathematics, 2015)
    Special family of non-bijective multivariate maps Fn of Zmⁿ into itself is constructed for n = 2,3, ... and composite m.The map F is injective on Ωn = {x|x1+x2+: : : xn ∈ Zm*} and solution of the equation Fn(x) = b, x ∈ ...
  • On the units of integral group ring of Cn × C₆ 
    Küsmüş, Ö. (Algebra and Discrete Mathematics, 2015)
    There are many kind of open problems withvarying difficulty on units in a given integral group ring. In thisnote, we characterize the unit group of the integral group ring of Cn × C₆ where Cn = 〈a: aⁿ = 1〉 and C₆ = 〈x: x⁶ ...
  • Quivers of 3×3 exponent matrices 
    Dokuchaev, M.; Kirichenko, V.V.; Plakhotnyk, M. (Algebra and Discrete Mathematics, 2015)
    We show how to use generating exponent matrices to study the quivers of exponent matrices. We also describe the admissible quivers of 3×3 exponent matrices.
  • Serial group rings of finite groups. General linear and close groups 
    Kukharev, A.; Puninski, G. (Algebra and Discrete Mathematics, 2015)
    For a givenp, we determine when thepmodulargroup ring of a group from GL(n,q), SL(n,q) and PSL(n,q)-seriesis serial.
  • To the 60th anniversary of E. Zelmanov 
    Автор відсутній (Algebra and Discrete Mathematics, 2015)
    On September 7, 2015, a distinguished mathematician, one of thefounders of our journal, Efim Isaakovich Zelmanov, turned 60. He wasborn in Khabarovsk, Soviet Union (now Russian Federation), while hismother grew up in the ...
  • Universal property of skew PBW extensions 
    Acosta, J,.P.; Lezama, O. (Algebra and Discrete Mathematics, 2015)
    In this paper we prove the universal property of skew $PBW$ extensions generalizing this way the well known universal property of skew polynomial rings. For this, we will show first a result about the existence of this ...
