引入了拟BCK-代数的扰动模糊理想的概念,刻画了拟BCK-代数的扰动模糊理想的特征;给出拟BCK-代数上的一个扰动模糊集成为扰动模糊理想的条件;构造了由给定扰动模糊集生成的最小扰动模糊理想;研究了拟BCK-代数的扰动模糊理想的同态性质。
The concept of disturbing fuzzy ideals of pseudo-BCK algebras is introduced, the characterizations of disturbing fuzzy ideals of a pseudo-BCK algebra are described. The conditions for a disturbing fuzzy set of a pseudo-BCK algebra to be a disturbing fuzzy ideal are given. Given a disturbing fuzzy set A of a pseudo-BCK algebra, the least disturbing fuzzy ideal containing A is constructed. The homomorphic properties of fuzzy ideals of a pseudo-BCK algebra are studied.
