Commutative semigroups satisfying the equation and having only two -invariant congruences for an automorphism group are considered. Some classes of these semigroups are characterized and some other examples are constructed.

Non-Archimedean f-rings need not be p-distributive. Moreover, if {d|i} is a subset of a non-Archimedean f-ring and a ≥ 0, the elements a v d and v ad need not be equal. We prove, however, that the difference is an infinitely small element when the ring has a strong unity.
