A radical extension of the category of $S$-sets
Let S-Set be the category of $S$-sets, sets together with the actions of a semigroup $S$ on them. And, let S-Pos be the category of $S$-posets, posets together with the actions compatible with the orders on them. In this paper we show that the category S-Pos is a radical extension of S-Set; that is there is a radical on the category S-Pos, the order desolator radical, whose torsion-free class i...
متن کاملExtension of LCZ Sequence Sets
In this paper, given a q-ary LCZ sequence set with parameters (N,M,L, ǫ) and even q, we construct another q-ary LCZ sequence set with parameters (2N, 2M,L, 2ǫ) when q is even. Especially for odd L such that L|N , if a q-ary optimal LCZ sequence set with parameters (N,M,L, 1) is used, the new set with parameters (2N, 2M,L, 2) can be optimal in terms of the set size.
متن کاملm-Polar Fuzzy Sets: An Extension of Bipolar Fuzzy Sets
Recently, bipolar fuzzy sets have been studied and applied a bit enthusiastically and a bit increasingly. In this paper we prove that bipolar fuzzy sets and [0,1](2)-sets (which have been deeply studied) are actually cryptomorphic mathematical notions. Since researches or modelings on real world problems often involve multi-agent, multi-attribute, multi-object, multi-index, multi-polar informat...
متن کاملExtension of Crisp Functions on Neutrosophic Sets
In this paper, we generalize the definition of Neutrosophic sets and present a method for extending crisp functions on Neutrosophic sets and study some properties of such extended functions.
متن کاملFour-Valued Extension of Rough Sets
Rough set approximations of Pawlak [15] are sometimes generalized by using similarities between objects rather than elementary sets. In practical applications, both knowledge about properties of objects and knowledge of similarity between objects can be incomplete and inconsistent. The aim of this paper is to define set approximations when all sets, and their approximations, as well as similari...
