In this manuscript, we introduce and study co-coatomically ps-supplemented modules. On condition that each co-coatomic submodule of an T-module A has a ps-supplement within A, then A is termed co-coatomically ps-supplemented. Each radical module is co-coatomically ps-supplemented module. On condition that each left T-module is PS-coinjective, then each left T-module is co-coatomically ps-supplemented. We show that on condition that A is semilocal and Rad(A)≪A, for A, being a cocoatomically ps-supplemented module is equivalent to being ps-supplemented. If A is co-coatomically ps-supplemented T-module, at that case the module A/(〖Soc〗_P (A) ) has each of its coatomic submodules as direct summands. Assuming T to be a left SI-ring with an essential socle, it implies that each left T-module is co-coatomically ps-supplemented.

Bu makalede eş-eşatomik ps-tümlenmiş modülleri tanımlıyor ve calışıyoruz. Bir A T-modülünün her eş-eşatomik alt modülü A’da bir ps-tümleyene sahipse bu takdirde A T-modülü,eş-eşatomik ps-tümlenmiş modül olarak adlandırılır. Her radikal modül eş-eşatomik ps-tümlenmiş modüldür. Her sol T-modül PS-koinjektif ise bu takdirde her sol T-modül eş-eşatomik ps-tümlenmiştir. Biz gösterdik ki, A yarıyerel ve Rad(A)≪A ise A’nın eş-eşatomik ps-tümlenmiş modül olması icin gerek ve yeter şart A’nın ps-tümlenmiş olmasıdır. Eğer A eş-eşatomik ps-tümlenmiş T-modül ise bu takdirde A/(〖Soc〗_P (A) )‘nın her eşatom alt modülü direkt toplam terimidir. T halkasının büyük desteğe sahip bir sol SI-halka olduğunu varsayarsak her sol T-modül eş-eşatomik ps-tümlenmiş T-modül olur.
