可判定性与k-正则序列

Decidability and k-Regular Sequences

Daniel Krenn, Jeffrey Shallit

摘要:

本文研究了一类涉及k-正则序列的自然决策问题。具体而言,它们产生于-增长率的上下限;特别是有界性,-图像,-规律性(由确定性有限自动机识别)的原像,和-因素,如广场和回文等序列。我们证明了决策问题是不可判定的。

英文摘要:

In this paper we consider a number of natural decision problems involving k-regular sequences. Specifically, they arise from - lower and upper bounds on growth rate; in particular boundedness, - images, - regularity (recognizability by a deterministic finite automaton) of preimages, and - factors, such as squares and palindromes of such sequences. We show that the decision problems are undecidable.
