On a theorem of Stelzer for some classes of mixed groups

Simion Breaz

We identify some classes $C$ of mixed groups such that if $G \in C$ has the cancellation property then the Walk-endomorphism ring of $G$ has the unit lifting pro…

A mixed version for a Fuchs' Lemma

Simion Breaz

We prove a version for mixed groups for a Fuchs' result about connections between the cancellation property of a group and the unit lifting property of its (Walk-)endomorphism ring…

The ascent-descent property for $2$ -term silting complexes

Simion Breaz

We will prove that over commutative rings the silting property of $2$ -term complexes induced by morphisms between projective modules is preserved and reflected by faithfully flat e…

Strictly invariant submodules

Simion Breaz, Grigore Călugăreanu, Andrey Chekhlov

If $M$ is an $R$ -module, we study the submodules $K \leq M$ with the property that $K$ is invariant with respect to all monomorphisms $K \to M$ . Such submodules are called \t…
