Abstract
The concept of normal congruence on a weakly ample semigroup, S, is introduced and the maximum and minimum admissible congruences whose trace is the normal congruence, ?, on a weakly ample semigroup, S, are characterized in this paper. Some results about congruences on ample semigroups are generalized to weakly ample semigroups.
