Abstract

Post's Embedding Problem is a new variant of Post's Correspondence Problem where words are compared with embedding rather than equality. It has been shown recently that adding regular constraints on the form of admissible solutions makes the problem highly non-trivial, and relevant to the study of lossy channel systems. Here we consider the infinitary version and its application to recurrent reachability in lossy channel systems.
