关于二阶Monadic Monoidal和Groupoidal量词

On Second-Order Monadic Monoidal and Groupoidal Quantifiers

Juha Kontinen, Heribert Vollmer

摘要:

我们研究逻辑定义的二阶monadic monoidal和groupoidal量词。这些都是广义量词定义的幺半群和广群字的问题,等价地,由正规和上下文无关的语言。我们给出了一个计算分类的表达能力,这些逻辑字符串不同的内置谓词。特别是,我们表明,ATIME(n)可以在逻辑上的特点是在二阶monadic monoidal量词。

英文摘要:

We study logics defined in terms of second-order monadic monoidal and groupoidal quantifiers. These are generalized quantifiers defined by monoid and groupoid word-problems, equivalently, by regular and context-free languages. We give a computational classification of the expressive power of these logics over strings with varying built-in predicates. In particular, we show that ATIME(n) can be logically characterized in terms of second-order monadic monoidal quantifiers.
