Belirli alt modüllerinin tümleyeni toplanan olan modüller

Bu çalışmada p-alt modüllerinin tümleyeni dik toplanan olan modüller araştırılmıştır. Dik toplam ve dik toplanan gibi modül teorik özellikler incelenmiştir. Dik toplamın aksine, bu modül özelliği dik toplananlara taşınmadığından, hangi koşullar altında ilgili özelliğin dik toplananlara aktarıldığı üzerinde çalışılmıştır. Elde edilen sonuçları niteleyen örneklere yer verilmiştir.

When some complement of a certain submodule is a summand

In this study, the modules whose p-submodules have a complement which is a direct summand are explored. The module theoretical properties such as direct sums and summands are investigated. As opposed to direct sums, this condition does not transfer to the direct summands. Thus, it is examined that under what conditions the direct summands fulfill the property. Examples are given to demonstrate the results.

Keywords:

Complement submodule, extending module projection invariant submodule.,
