Choi, Chang Woo; Smith, Patrick F. On endomorphisms of multiplication modules. (English) Zbl 0820.13003 J. Korean Math. Soc. 31, No. 1, 89-95 (1994). Let \(R\) be a commutative ring with identity. An \(R\)-module \(M\) is called a multiplication module if for every submodule \(N\) of \(M\) there exists an ideal \(I\) of \(R\) such that \(N= IM\). If \(M\) is a finitely generated multiplication module then every endomorphism of \(M\) is given by multiplication by an element of \(R\), and a partial converse is given for finitely generated modules. In addition, if \(M\) is an indecomposable multiplication module which satisfies dcc on multiplication submodules then any non-nilpotent endomorphism of \(M\) is an automorphism, and hence \(\text{End}(M)\) is a local ring.
