Semigroup Algebras of Finite Type-A Semigroups
Guo Xiao-jiang · Journal of Jiangxi Normal University · 2010
Semigroup algebras of finite type-A semigroups are studied by group representation theory.It is proved that semigroup algebras of finite type-A semigroups are isomorphic to direct sums of contracted semigroup algebras of finite weak Brandt semigroups.And it is obtained that semigroup algebras of finite type-A semigroups contain identities.These results extend the related results on semigroup algebras of finite inverse semigroups.
