Dear author of RP2008, First, thank you again for publishing your work at the Reachability Problems (RP) conference in the past. This year RP2019 (13th edition) has gathered an impressive list of PC members and invited speakers. We have ambitious goals for the 2019 edition of RP and we decided to communicate with all authors of accepted papers at the RP event in the past. We feel that there is a momentum today in our community, and we plan to leverage it to make this edition a great event. As you have seen, the PC and the invited speakers reflect the multiple nature of our discipline (among which Automata and languages, Control theory, Game theory, and Verification), and we very much hope that the scientific program will reflect it too. We expect that this will give RP19 a unique flavour in the landscape of scientific events in our community. Important dates are: Abstract: May 31 2019 Submission: June 7 2019 Notification: July 12 2019 Final Version: July 16 2019 For this reason, we would like to encourage you to submit a work of yours at the conference. If we may, we would also like to ask you to advertise the conference around you; you are indeed also the best placed to spread the word and attract good researchers to the conference. Both the poster and the flyers are to download from the website: https://sites.uclouvain.be/rp2019/ RP TOPICS: The conference is specifically aimed at gathering together scholars from diverse disciplines and backgrounds interested in reachability problems that appear in ● Algebraic structures ● Automata Theory and Formal Languages ● Computational Game Theory ● Concurrency and Distributed computation ● Decision Procedures in Computational models ● Hybrid Dynamical Systems ● Logic and Model Checking ● Verification of Finite and Infinite-state Systems Topics of interest include (but are not limited to): reachability problems in infinite state systems, rewriting systems, dynamical and hybrid systems; reachability problems in logic and verification; reachability analysis in different computational models, counter timed/ cellular/ communicating automata; Petri nets; computational and combinatorial aspects of algebraic structures (semigroups, groups and rings); frontiers between decidable and undecidable reachability problems; predictability in iterative maps and new computational paradigms. Finally, we are committed to maintain the registration fees of all participants (and in particular students) to a strict minimum. We will also do our best to organize nice social events to enjoy Brussels, and enhance collaborations and interaction among participants. Recall also that Brussels is easy to access, and a nice place to stay and enjoy at that time of the year. We are looking forward to see you in Brussels!
