TitreThe Power of Priority Channel Systems 
RésuméWe introduce Priority Channel Systems, a new class of channel systems where messages carry a numeric priority and where higher-priority messages can supersede lower-priority messages preceding them in the fifo communication buffers. The decidability of safety and inevitability properties is shown via the introduction of a priority embedding, a well-quasi-ordering that has not previously been used in well-structured systems. We then show how Priority Channel Systems can compute Fast-Growing functions and prove that the aforementioned verification problems are F_{epsilon_{0}}-complete. Joint work with Christoph Haase and Philippe Schnoebelen. A short version was presented at Concur 2013; see http://arxiv.org/abs/1301.5500 for the full paper.
