Abstract
We investigate the nearunanimity problem: given a finite algebra, decide if it has a nearunanimity term of finite arity. We prove that it is undecidable of a finite algebra if it has a partial nearunanimity term on its underlying set excluding two fixed elements. On the other hand, based on Rosenberg’s characterization of maximal clones, we present partial results towards proving the decidability of the general problem.
