Finite permutable Putcha semigroups
A semigroup S is called a permutable semigroup ifao/ 3 = /?o a is satisfied for all congruences a and /3 of S. A semigroup is called a Putcha semigroup if it is a semilattice of axchimedean semigroups. In this paper we deal with finite permutable Putcha semigroups. We describe the finite permutable...

| Tartalmi kivonat: | A semigroup S is called a permutable semigroup ifao/ 3 = /?o a is satisfied for all congruences a and /3 of S. A semigroup is called a Putcha semigroup if it is a semilattice of axchimedean semigroups. In this paper we deal with finite permutable Putcha semigroups. We describe the finite permutable archimedean semigroups and finite permutable semigroups which are semilattices of a group and a nilpotent semigroup. |
