Abstract: The main aim of this paper is to study admissible congruences on a type B semigroup. Some properties of kernels of admissible congruences on a type B semigroup are given, and a characterization of the minimum admissible congruence on a type B semigroup is obtained. In particular, some characterizations of admissible congruences with E property on a type B semigroup are given, and some results are obtained.

Key words: minimum admissible congruences, E-unitary, kernel, type B semigroups
