Power cancellation of modules [PDF]

open access: yesPacific Journal of Mathematics, 1986
Let Mod-R (resp. \(Mod_ f-R)\) denote the category of unital right (resp. finitely generated) R-modules. \(X\in Mod_ f-R\) satisfies ''power cancellation'' if for all M,N\(\in Mod-R\), \(M\oplus X\cong N\oplus X\Rightarrow M^{(t)}\cong N^{(t)}\) for some ...
