Structure of the semigroup OT n

  • Published:
Ukrainian Mathematical Journal Aims and scope

We study the structure of the semigroup OT n , which is a unique (up to an isomorphism) R-section of the semigroup T n . For this semigroup, we describe Green relations, determine regular and nilpotent elements, describe maximal nilpotent subsemigroups, and determine the unique irreducible system of generatrices and maximal subsemigroups.
