Halkalarda elemanların hırano tersleri
Özet
This thesis consists of four chapters. The first chapter is the introduction of the thesis. In the second chapter, basic definitions which are necessary for the thesis are given. In the third chapter, the relations among Hirano inverses, strongly Drazin in¬verses and Drazin inverses in rings, various characterizations and some properties are given. In the fourth chapter, the relations between generalized Hirano inverses and generalized Drazin inverses in rings are investigated. Matrices over projective-free rings are studied for generalized Hirano inverses. Also Cline's formula for generalized Hirano inverses and some properties of these inverses are examined.
