Keywords:
quasi hamiltonian semigroups; super hamiltonian semigroups; quasi commutative semigroups; quasi-groups; strong semilattices of semigroups
quasi hamiltonian semigroups; super hamiltonian semigroups; quasi commutative semigroups; quasi-groups; strong semilattices of semigroups
Summary:
The concept of super hamiltonian semigroup is introduced. As a result, the structure theorems obtained by A. Cherubini and A. Varisco on quasi commutative semigroups and quasi hamiltonian semigroups respectively are extended to super hamiltonian semigroups.
