本文研究了格的TL-模糊理想. 利用生成TL-模糊理想, 证明了一个模格的全体TM-模糊理想形成一个完备的模格. 此外, 利用L-模糊集的投影和截影, 获得了将直积格的TL-模糊理想表示成分量格的TL-模糊理想的L-直积的一个充分必要条件. 所得结果进一步推广和发展了格的模糊理想的理论. |

Abstract: |
In this paper, we study TL-fuzzy ideals in lattices. By a TL-fuzzy ideal generated by an L-fuzzy subset, we prove that the lattice of TM-fuzzy ideals in a modular lattice is a complete modular lattice. Moreover, using the projection and the cut shadow of an L-fuzzy set, we obtain necessary and sufficient conditions for a TL-fuzzy ideal of a Cartesian product of lattices to be a T-product of TL-fuzzy ideals of lattices. Our results generalize and develop the fuzzy ideal theory in lattices. |
