Master's Thesis by "Hadeel khalid Mohammed Qasim" Department of Mathematics Discussion of the Master's Thesis Submitted to the College of Computer Science and Mathematics, Department of Mathematics, Entitled: “On TT-nil clean rings” supervised by  Prof. Dr. Nazar Hamdoon shuker In this thesis, we introduce the notion of  TT-nil clean rings (TTNC-ring for short). A  NC-ring is a ring in which for every  in     or   where  is a tripotent    is nilpotent and   The fundamental structural properties of these rings are investigated in detail. Furthermore,  the relationships between TT-nil clean rings and  other known types of rings in the theory such as strongly 2-nil clean [Read More]
