Cyclic-quasi-injective for Finite Abelian Groups
Cyclic-quasi-injective for Finite Abelian Groups
We investigate the conditions for a finite abelian group $G$ under which any cyclic subgroup $H$ and any group homomorphism $f \in \operatorname{Hom}(H,G)$ can be extended to an endomorphism $F \in \operatorname{End}(G)$. As a result, we provide necessary and sufficient conditions for such a group $G$ and we compute the …
