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.

Soft ideals and soft filters of soft ordered semigroups

TL;DR: It is shown that soft ordered semigroups over an ordered semigroup are actually soft ordered subsemigroups of (S,A) and that restricted complement of a soft filter is a soft prime ideal of (A).
