Abstract:
We study the problem of characterizing clones on a three-element set by hyperidentities. We prove that there exists a hyperidentity separating any clone of quasilinear functions defined on the set $\{0,1,2\}$ each of them is either a selector or such that all its values belong to $\{0,1\}$ from any noncreative clone constituted by such functions incomparable with the initial clone.
