Multi-invariant sets on compact abelian groups

Let G be a finite-dimensional connected compact abelian group. Generalizing previous results, dealing with the case of finite-dimensional tori, a full characterization is given herewith of those commutative semigroups 2 of continuous endomorphisms Σ of G which satisfy the following property: The only infinite closed Σ-invariant subset of G is G itself.
