Gorbatkov.Interassociates of a free semigroup on two generators, Mat.Stud.41 (2014), 139-145.For any semigroup (S; •) let (S; •) be a semigroup defined on the same set.Semigroup (S; •) is called an interassociate of (S; •) if the following identities hold x • (y • z) = (x • y) • z and x • (y • z) = (x • y) • z.All interassociates of the free semigroup over the two-element alphabet are described.А.
