Inspired by this idea, we aim to create a route from delta(ss)-perfect rings to delta(ss)-perfect modules. A module W is said to be delta(ss)-perfect if each factor module is of a projective delta(ss)-cover. Owing to this goal, we obtain new relations for projective (amply) delta(ss)-supplemented and delta(ss)-lifting modules. Also, we present various characterization theorems for a (projective) module to be delta(ss)-perfect.eninfo:eu-repo/semantics/closedAccesssemisimple module(amply) delta(ss)-supplemented moduledelta(ss)-lifting moduleleft delta(ss)-perfect ringdelta(ss)-perfect moduleArticle38165559556610.2298/FIL2416559O2-s2.0-85207840842Q3WOS:001337757200001Q2
