【摘要】 证明了任一型A半群在其幂等元半格上的局部化存在且在同构意义下唯一,从而将局部化推广到型A半群上,接着证明了该局部化就是它的最大可消幺半群同态像,并由此导出了型A半群的最小可消幺半群同余的一个刻画.更多还原

【Abstract】 In this paper,the existence and uniquenss of localization of a type-A semigroup on its idempotent semilattice are proved.The localization is the maximum cancellative monoid homomorphic image of the type-A semigroup.The minimum cancellative monoid congruence on the semigroup is also characterized.更多还原
