In this paper we show a series of results related to the decidability and expressive power of quantifier-free first order logical formulas containing language membership predicates (for the classes of regular and visibly push-down languages), string concatenation, letter-count and string-length functions, as well as linear integer arithmetic.

摘要

In this paper we show a series of results related to the decidability and expressive power of quantifier-free first order logical formulas containing language membership predicates (for the classes of regular and visibly push-down languages), string concatenation, letter-count and string-length functions, as well as linear integer arithmetic.
