A Subclass of LTL with the Freeze Quantifier Translatable into Register Automata

Abstract (in Japanese) (See Japanese page) 
(in English) Register automaton (abbreviated as RA) is an extension of finite automaton by adding
registers storing data values. RA has good properties such that the membership and emptiness problems are decidable. LTL with the freeze quantifier (abbreviated as LTL$^downarrow$) is a counterpart of RA. However, the expressive power of LTL$^downarrow$ is too high to be applied to automatic verification. In this paper, we propose a subclass of LTL$^downarrow$ that can be translated into RA and provide a translation from this subclass to RA. In a general LTL$^downarrow$ formula, a conjunct $psi_1 wedge psi_2$ cannot be simulated by RA. The proposed subclass is defined by prohibiting at least one of $psi_1$ and $psi_2$ containing freeze quantifier or temporal operator other than $X$.
