The "pipeline" for building such computer models includes image analysis (segmentation, registration, filtering), geometric modeling (surface and volume mesh generation), large-scale … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2011-fall/ END:VEVENT BEGIN:VEVENT UID:20111027T160000-andrei-caldararu@math.utah.edu DTSTART;TZID=America/Denver:20111027T160000 DTEND;TZID=America/Denver:20111027T170000 DTSTAMP:20260821T120902Z SUMMARY:The Pfaffian-Grassmannian derived equivalence DESCRIPTION:Speaker: Andrei Caldararu\, University of Wisconsin, Madison\n\nString theory relates certain seemingly different manifolds through a relationship called mirror symmetry. Discovered about 25 years ago, this story is still very mysterious from a mathematical point of view. Despite the name, mirror symmetry is not entirely symmetric -- several distinct spaces can … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2011-fall/ END:VEVENT BEGIN:VEVENT UID:20111117T160000-eitan-tadmor@math.utah.edu DTSTART;TZID=America/Denver:20111117T160000 DTEND;TZID=America/Denver:20111117T170000 DTSTAMP:20260821T120902Z SUMMARY:A new model for self-organized dynamics: from particle to hydrodynamic descriptions DESCRIPTION:Speaker: Eitan Tadmor\, University of Maryland\n\nSelf-organized dynamics is driven by "rules of engagement", which describe how each agent interacts with its neighbors. They consist of long-term attraction, mid-range alignment and short-range repulsion. Many self-propelled models are driven by the balance between these three forces, which yield … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2011-fall/ END:VEVENT BEGIN:VEVENT UID:20111208T160000-keith-conrad@math.utah.edu DTSTART;TZID=America/Denver:20111208T160000 DTEND;TZID=America/Denver:20111208T170000 DTSTAMP:20260821T120902Z SUMMARY:Why is the Riemann Hypothesis Important? DESCRIPTION:Speaker: Keith Conrad\, University of Connecticut\n\nAll mathematicians have heard that the Riemann Hypothesis is a significant open problem, but why is it such a big deal? One can name plenty of older unsolved problems in number theory that get far less publicity. We care about the Riemann Hypothesis because it is connected to a large number of … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2011-fall/ END:VEVENT END:VCALENDAR
