A recent line of work to improve the secrecy capacity within wiretap gaussian channel has introduced a new lattice invariant called secrecy gain. Belfiore and Sol´e made a conjecture about the point at which the the secrecy gain is maximum. Verified by most unimodular lattices, t...

We consider the class F of endo-Artinian modules, i.e. the modules M which satisfying the descending chain condition for endomorphic images: any descending chain is stationary, where . Let A be the class of Artinian modules. It is clear that every Artinian R-moduleM is endo-A...

We consider the class E of endo-Noetherian modules, i.e. the modules M which satisfying the ascending chain condition for endomorphic kernels: any ascending chain Kerf1 Kerf2 Kerfn is stationary, where fi 2 End(M). Let N be the class of Noetherian modules. It is clear that every...
