In the present paper, we studied Ξ©-monoids. We define and characterize the Ξ©-semigroups as a universal algebra which is a semigroup and in which there is given a system of binary operations Ξ© satisfying the associative condition: ((π‘₯, 𝑦), 𝑧)𝛽 = (π‘₯, (𝑦, 𝑧)𝛽)𝛼 for all π‘₯, 𝑦, 𝑧 ∈ 𝑆 and for each pair of binary operations 𝛼, 𝛽.

Keywords: 𝛀-semigroup; Finite derivation type; String-rewriting systems; Derivation graph; Homotopy.
