Maximal, irreducible and prime soft ideals of BCK/BCI-algebra
Acar, Ummahan; Öztürk, Yalçın (Hacettepe Univ, Fac Sci, 2015)In this paper, the notions of soft irreducible, prime and maximal soft ideals, irreducible, prime and maximal soft idealistic over on BCK/BCI-algebras are introduced, and several examples are given to illustrate. Relations ... -
A NOTE ON SOFT MODULES
Yucel, Canan Celep; Acar, Ummahan (Ankara Univ, Fac Sci, 2017)In this paper, essential soft submodule and complement of a soft submodule in a soft module are defined. The basic properties of such soft submodules are obtained. The notion of complement of soft submodules on soft modules ... -
On Rings whose Quasi Projective Modules Are Projective or Semisimple
Orhan Ertaş, Nil; Acar, Ummahan (RGN PUBL, 2021)For two modules M and N, P-M(N) stands for the largest submodule of N relative to which M is projective. For any module M, P-M(N) defines a left exact preradical. It is given some properties of P-M(N). We express P-M(N) ... -
Soft sets and soft rings
Acar, Ummahan; Koyuncu, Fatih; Tanay, Bekir (Pergamon-Elsevier Science Ltd, 2010)Molodtsov (1999) introduced the concept of soft sets in [1]. Then, Maji et al. (2003) defined some operations on soft sets in [2]. Aktas and Cagman (2007) defined the notion of soft groups in [3]. Finally, soft semirings ...
