Abstract
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 \(\mathscr Q\mathscr D_{\mathrm{cd}}\).
