  • Characterization of regular convolutions 
    Sagi, S. (2018)
    A convolution is a mapping C of the set Z + of positive integers into the set P(Z +) of all subsets of Z + such that,for any n ∈ Z +, each member of C(n) is a divisor of n. If D(n) is the set of all divisors of n, for any ...
  • Construction of a complementary quasiorder 
    Jakubíková -Studenovská, D.; Janičková, L. (ДЗ "ЛНУ імені Тараса Шевченка", 2018)
    For a monounary algebra A = (A, f) we study the lattice Quord A of all quasiorders of A, i.e., of all reflexive and transitive relations compatible with f. Monounary algebras (A, f) whose lattices of quasiorders are ...
  • Lattice rings: an interpretation of L-fuzzy rings as habitual algebraic structures 
    Kurdachenko, L. A; Subbotin, I. Ya.; Yashchuk, V. S. (ДЗ "ЛНУ імені Тараса Шевченка", 2017)
    In this paper, we introduce some algebraic structure associated with rings and lattices. It appeared as the result of our new approach to the fuzzy rings and L-fuzzy rings where L is a lattice. This approach allows us to ...
