在本文中，我们定义了无量化器的最小固定点函数（QFLFP），并认为它们是模拟语音过程（解释为输入输出映射）的适当且有价值的方法。这些函数的特征在于对图的一阶逻辑解释，提供了与观察到的类型学的紧密配合，捕获了局部和远距离现象，但也以理想的方式进行了限制。也就是说，QFLFP逻辑函数近似于确定性有限状态转换器的计算，这被认为是形成音位过程的限制性假设。
In this paper we define quantifier-free least fixed point functions (QFLFP) and argue that they are an appropriate and valuable approach to modeling phonological processes (construed as input-output maps ). These functions, characterized in terms of first order logic interpretations over graphs, provide a close fit to the observed typology, capturing both local and long-distance phenomena, but are also restrictive in desirable ways. Namely, QFLFP logical functions approximate the computation of deterministic finite-state transducers, which have been argued to form a restrictive hypothesis for phonological processes.
