Abstract

The aim of this paper is to classify all monogenic ternary semigroups,
up to isomorphism. We divide them to two groups: finite and infinite.
We show that every infinite monogenic ternary semigroup is isomorphic to
the ternary semigroup O, the odd positive integers with ordinary addition.
Then we prove that all finite monogenic ternary semigroups with the same
index and the same period are isomorphic. We also investigate structure of
finite monogenic ternary semigroups and we prove that any finite monogenic
ternary semigroup is isomorphic to a quotient ternary semigroup.
