Let $$\Lambda$$ be a class of Abelian groups. A group $$A\in\Lambda$$ is said to be determined by its endomorphism semigroup $$E^\star(A)$$ in the class $$\Lambda$$ if every isomorphism $$E^\star(A)\cong E^\star(B)$$
, where $$B\in\Lambda$$
, implies the isomorphism $$A\cong B$$
. The paper describes those Abelian groups in the class $$\mathscr Q\mathscr D_{\mathrm{cd}}$$ of completely decomposable quotient divisible Abelian groups which are determined by their endomorphism semigroups in the class $$\mathscr Q\mathscr D_{\mathrm{cd}}$$

具有同构内同态半群的完全可分解商可分阿贝尔群
令 $$\Lambda$$ 是一类阿贝尔群。如果每个同构 $$E^\star( A)\cong E^\star(B)$$ ,其中 $$B\in\Lambda$$ ,暗示同构 $$A\cong B$$ 。该论文描述了类 $$\mathscr Q\mathscr D_{\mathrm{cd}}$$ 中的完全可分解商可分阿贝尔群的那些阿贝尔群,它们由类 $$\mathscr Q\mathscr 中的自同态半群决定D_{\mathrm{cd}}$$ 。
