Dear CAST Members and other Interested Parties, We are arranging an IFAC Workshop on *Thermodynamics and Mathematical Systems Theory* to take place in Lyon July-13-16, 2013. You can find information in the attached flyer and the on the webpage *http://www-lagep.univ-lyon1.fr/test/nonvu/fc/TFMST2013/* The objective is to gather interested researchers to discuss how to combine tools from mathematical systems theory, circuit theory and irreversible thermodynamics to form a foundation for a physical approach to control system design. We are very open minded at this point and the IPC will consider practical applications as well theoretical contributions. Papers on classical thermodynamics, Hamiltonian systems, quantum control, molecular systems and Kinetic Monte Carlo systems are in various stages of preparation at present. Paper submissions are made on the IFAC paperplaza http://ifac.papercept.net/conferences/scripts/start.pl Please note the short lead time. The papers can be quite short and should primarily provide entry-points for spirited discussions. The IPC expect to select a few papers for plenary style presentations. The rest of the papers will be allocated a 5 minute slot for oral presentation of posters to be discussed in the afternoon. Note that Tour de France will pass through Lyon on July 13 and that Bastille Day will be celebrated this weekend as well (July-13-14) so that there will some pressure on hotel rooms. We have made a block of reservations already in Residence Villemancy. It should be a good time. Lyon os the food capital of France (maybe the world?) and there are many things to visit there and in the immediate vicinity. Please let us know if you are interested in contributing to the workshop so that we can expand our bookings estimate at Villemanzy. Any questions about the workshop can be directed to the organizers. Best wishes for a peaceful Holiday and looking forward to see you in Lyon mes amis !! Francoise, Bernard, Denis and Erik *(Les Trois Mousquetaires plus Dartagnan)* -- B.
