Katok and discuss first r esults. We show the flexibility of the entropy with respect to the Liouvil le measure and topological entropy for geodesic flow on negatively curved surfaces with fixed genus and total area (joint with A. Katok). Also\, we point out some restrictions which come from additionally fixing a conforma l class of metrics (joint with T. Barthelme).  If time permits\, we descri be a flexibility result for Lyapunov exponents for smooth expanding maps o n a circle of fixed degree.\n DTSTART:20170517T173000Z DTEND:20170517T183000Z LOCATION:Room 920\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:Alena Erchenko\, Penn State URL:/channels/event/alena-erchenko-penn-state-268087 END:VEVENT END:VCALENDAR
