本文证明了当半群 S 的幂等元集为右正则带时,S 的左拟内射性与左内射性是一致的;进而证明了半群的拟内射性与内射性是一致的.
This paper proves that when the idempotent set of semigroups S is a right regular band, the left and right injective properties of S are consistent with the left injective property. Furthermore, it is proved that the quasi-injective and injective properties of semigroups are consistent.
