    • On extensibility of some homomorphisms 

      Jabłoński, Wojciech (1999)
      The paper deals with a system of functional equations connected with the determination of some class of homomorphisms of uniquely divisible abelian semigroup (G,+) into the group L[1][s] or L[1][∞]. We give a necessary ...
    • On some subsemigroups of the group L[1][8] 

      Jabłoński, Wojciech (1997)
      In this paper we generalize the results concerning determination of some form subsemigroups of the group L[1][8]. We show that for s ≥ 4 + 2i there are no subsemigroups Z[1][s,8](f) and T[1][s,8](g). We determine all ...
