非结合MV-代数中的剩余

Residuation in non-associative MV-algebras

Ivan Chajda, Helmut Länger

摘要:

每个MV-代数都可以转化为满足可除性和双重否定律的剩余格。在我们以前的论文中,我们引入了NMV-代数的概念,它是MV-代数的非结合修改。一个自然的问题是,一个NMV-代数是否也可以转换成一个剩余结构。与MV-代数相反,NMV-代数不是基于格,而是仅基于有向偏序集,并且二元运算不需要是结合的,因此我们不能期望得到剩余格,而只能得到一个本质上较弱的结构,称为条件剩余偏序集。考虑几个额外的自然条件,我们证明了每个NMV-代数可以转换成这样的结构。反过来,每个这样的结构都可以组织成一个NMV-代数。此外,我们研究一个代数的更强版本,其中二元运算甚至是单调的。我们表明,这样的代数可以组织成一个剩余偏序集,相反,每一个剩余偏序集可以在这个结构转换。

英文摘要:

It is well known that every MV-algebra can be converted into a residuated lattice satisfying divisibility and the double negation law. In our previous papers we introduced the concept of an NMV-algebra which is a non-associative modification of an MV-algebra. The natural question arises if an NMV-algebra can be converted into a residuated structure, too. Contrary to MV-algebras, NMV-algebras are not based on lattices but only on directed posets and the binary operation need not be associative and hence we cannot expect to obtain a residuated lattice but only an essentially weaker structure called a conditionally residuated poset. Considering several additional natural conditions we show that every NMV-algebra can be converted in such a structure. Also conversely, every such structure can be organized into an NMV-algebra. Further, we study a bit more stronger version of an algebra where the binary operation is even monotonous. We show that such an algebra can be organized into a residuated poset and, conversely, every residuated poset can be converted in this structure.
