Soft set theory—First results
TLDR
The main purpose of this paper is to introduce the basic notions of the theory of soft sets, to present the first results of the the theory, and to discuss some problems of the future.Abstract:
The soft set theory offers a general mathematical tool for dealing with uncertain, fuzzy, not clearly defined objects. The main purpose of this paper is to introduce the basic notions of the theory of soft sets, to present the first results of the theory, and to discuss some problems of the future.read more

Generalized vague soft set and its applications
TL;DR: The concept of generalized intuitionistic fuzzy soft set and its operation which are equal, subset, union and intersection are introduced and an application of generalized vague soft sets in decision making with respect to degree of preference is illustrated.

On Soft Mappings
TL;DR: In this paper, the authors introduce soft continuous mappings which are defined over an initial universe set with a fixed set of parameters, and study soft open and soft closed mappings, soft homeomorphism and investigate some properties of these concepts.
