A note on homological systems

Representation Theory 2021-05-07 v1

Abstract

I give an elementary proof of the known fact that the category F(Δ)\mathfrak{F} \left( \Delta \right) of Δ\Delta -filtered modules, associated to a given finite homological system (Δ;Ω,),\left( \Delta ; \Omega , \leq \right) , is closed under direct summands.
