Abstract of talk
The notions of a semi-commutative semigroup and an abelian -polygon can be introduced by analogy with the notions of semi-commutative, abelian modules and rings.
A semigroup is called a semi-commutative semigroup if for any implies . A right -polygon is called abelian if for any and any any idempotent Using the notions of Baer’s conditions for modules I will introduce p.p.-Baer -polygons and prove that if is a p.p.-Baer -polygon, then the conditions for to be a reduced, symmetric, semicommutative and an abelian -polygon are equivalent.
