She is among the very few who deserve and enjoy genuine and deep respect from both research communities, in mathematics and education. … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2009-fall/ END:VEVENT BEGIN:VEVENT UID:20091029T160000-oscar-garcia-prada@math.utah.edu DTSTART;TZID=America/Denver:20091029T160000 DTEND;TZID=America/Denver:20091029T170000 DTSTAMP:20260821T120902Z SUMMARY:Geometry of surface group representations DESCRIPTION:Speaker: Oscar Garcia Prada\, Consejo Superior de Investigaciones Cientificas\n\nGiven a compact real surface S and a semisimple Lie group G, we consider the moduli space R(S,G) of representations of the fundamental group of S in G (sometimes called the character variety). This moduli space plays a central role in many problems in geometry, topology and physics. By considering a … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2009-fall/ END:VEVENT BEGIN:VEVENT UID:20091105T160000-sam-payne@math.utah.edu DTSTART;TZID=America/Denver:20091105T160000 DTEND;TZID=America/Denver:20091105T170000 DTSTAMP:20260821T120902Z SUMMARY:Nonarchimedean geometry DESCRIPTION:Speaker: Sam Payne\, Stanford University\n\nThe usual archimedean norm on the complex numbers and its associated analytic geometry (holomorphic functions and differential forms) have been fundamental tools for understanding the geometry and topology of complex algebraic varieties, for instance through Hodge theory and Lefschetz hyperplane … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2009-fall/ END:VEVENT BEGIN:VEVENT UID:20091112T160000-anthony-henderson@math.utah.edu DTSTART;TZID=America/Denver:20091112T160000 DTEND;TZID=America/Denver:20091112T170000 DTSTAMP:20260821T120902Z SUMMARY:Enhancing the Jordan canonical form DESCRIPTION:Speaker: Anthony Henderson\, University of Sydney\n\nIn undergraduate linear algebra, we learned the Jordan canonical form theorem: that every n x n complex matrix A is similar to an essentially unique matrix B which is block-diagonal with each block having a very simple form (a single eigenvalue repeated down the diagonal, ones on the super-diagonal, … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2009-fall/ END:VEVENT BEGIN:VEVENT UID:20091119T160000-george-papanicolaou@math.utah.edu DTSTART;TZID=America/Denver:20091119T160000 DTEND;TZID=America/Denver:20091119T170000 DTSTAMP:20260821T120902Z SUMMARY:Imaging with noise DESCRIPTION:Speaker: George Papanicolaou\, Stanford University\n\nIt is somewhat surprising at first that it is possible to locate a network of sensors from cross correlations of noise signals that they record. This is assuming that the speed of propagation in the ambient environment is known and that the noise sources are sufficiently diverse. If the sensor … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2009-fall/ END:VEVENT BEGIN:VEVENT UID:20091203T160000-florian-herzig@math.utah.edu DTSTART;TZID=America/Denver:20091203T160000 DTEND;TZID=America/Denver:20091203T170000 DTSTAMP:20260821T120902Z SUMMARY:Modular representations of p-adic groups DESCRIPTION:Speaker: Florian Herzig\, Northwestern University\n\nThe Langlands program relates complex representations of GL_n(Q_p) to Galois representations. For n = 1 this is explained by class field theory and for n = 2 this is closely related to the theory of modular forms. For general n, this is now understood by the work of Harris-Taylor and Henniart. In … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2009-fall/ END:VEVENT END:VCALENDAR
