在格蕴涵代数中提出了加既约元、乘既约元,研究了一类重要的格蕴涵代数Ln×L2中元素的不可约有限分解,并将这一理论用于研究Ln×L2上的几类格蕴涵代数方程,讨论了方程有解的充分必要条件,在此基础上给出了方程的具体解集。
In this paper, product-irreducible and sum-irreducible element of lattice implication algebra are proposed. The decomposition for the element of Ln×L2 which is an important lattice implication algebra are investigated, and used it to solve some special classes of lattice implication algebra of Ln×L2. The necessary and sufficient conditions to distinguish whether equations have solutions are discussed, on the base of it, the detailed solution set are given.
