This was originally proved by Desharnais et al. in 2003 using approximation techniques. Our proof uses descriptive set theory instead and less overall machinery. More importantly\, it give s new insight into the relation between logic and simulation. I will also present a 'nice' game characterization of simulation and bisimulation. I w ill explain what 'nice' means in this context. This is joint work with Bar tek Klin and Nathanaël Fijalkow with one important lemma pointed out to us by Roman Pol. There will be no category theory in this talk.\n\n\n\n DTSTART:20170207T200000Z DTEND:20170207T200000Z LOCATION:Room 920\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:Prakash Panangaden\, Âé¶¹´«Ã½ÍøÕ¾ URL:/mathstat/channels/event/prakash-panangaden-mcgill -university-265558 END:VEVENT END:VCALENDAR
