Abstract. The Regular Post Embedding Problem is a variant of Post’s Correspondence Problem where one compares strings with the subword relation and imposes additional regular con...
All the languages for querying semistructured data and the web use as an integral part regular expressions. Based on practical observations, finding the paths that satisfy those r...

Abstract. We consider linear time temporal logic enriched with semiextended regular expressions through various operators that have been proposed in the literature, in particular i...
