|Abstract||We define the pattern expressions as an extension of both regular expressions and patterns. We prove several properties of the new family of languages, similar to those of extended regex languages [Câmpeanu et al., Int. J. Found. Comput. Sci. 14 (6) (2003) 1007–1018]. We also define an automata system that recognizes these languages. Differences between regex and pattern expressions are also discussed.|
