Unambiguity in Automata Theory (Dagstuhl Seminar 21452)

dagrep_v011_i010_p057_21452.pdf (3 MB)


This report documents the program and the outcomes of Dagstuhl Seminar 21452 "Unambiguity in Automata Theory". The aim of the seminar was to improve the understanding of the notion of unambiguity in automata theory, especially with respect to questions related to the expressive power, succinctness, and the tractability of unambiguous devices. The main motivation behind these studies is the hope that unambiguous machines can provide a golden balance between efficiency - sometimes not worse than for deterministic devices - and expressibility / succinctness, which often is similar to the general nondeterministic machines. These trade-offs become especially important in the models where the expressiveness or the decidability status of unambiguous machines is different from that of nondeterministic ones, as it is the case, e.g., for register automata.
