| Abstract: | We characterize weak direct sums in BCI-algebras and discuss relations be tween weak direct sums and external direct sums by introducing the concepts of regular split homomorphisms, regular idempotent endomorphisms, and so on. |

| Keywords: | Regular idempotent endomophism regular split homomorphism regular split exact sequence weak direct sum external direct sum |
