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 ...
