This will include restrictions on the structure of orbit closures echoing Ratner's … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2016-fall/ END:VEVENT BEGIN:VEVENT UID:20161020T160000-bhargav-bhatt@math.utah.edu DTSTART;TZID=America/Denver:20161020T160000 DTEND;TZID=America/Denver:20161020T170000 DTSTAMP:20260821T120902Z SUMMARY:Bounding torsion in cohomology DESCRIPTION:Speaker: Bhargav Bhatt\, University of Michigan\n\nThe integral cohomology groups of a complex algebraic variety are one of the most fundamental invariants associated to the variety. The ranks of these groups are well understood in terms of the equations defining the variety, thanks to Hodge theory. However, the torsion tends to be much more … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2016-fall/ END:VEVENT BEGIN:VEVENT UID:20161110T160000-winfried-bruns@math.utah.edu DTSTART;TZID=America/Denver:20161110T160000 DTEND;TZID=America/Denver:20161110T170000 DTSTAMP:20260821T120902Z SUMMARY:Normaliz -- a tool for discrete convex geometry DESCRIPTION:Speaker: Winfried Bruns\, Universität Osnabrück\n\nNormaliz started in the late nineties as a tool for the normalization of affine monoids. Meanwhile it has grown into a versatile package for computations in discrete convex geometry: it computes lattice points in polyhedra, or, from a different perspective, solves linear diophantine systems of … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2016-fall/ END:VEVENT BEGIN:VEVENT UID:20161122T160000-giulia-sacc%C3%A0@math.utah.edu DTSTART;TZID=America/Denver:20161122T160000 DTEND;TZID=America/Denver:20161122T170000 DTSTAMP:20260821T120902Z SUMMARY:Compact Hyperkahler manifolds in algebraic geometry DESCRIPTION:Speaker: Giulia Saccà\, Stony Brook University\n\nHyperkahler (HK) manifolds appear in many fields of mathematics, such as differential geometry, mathematical physics, representation theory, and algebraic geometry. Compact HK manifolds are one of the building blocks for algebraic varieties with trivial first Chern class and their role in algebraic … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2016-fall/ END:VEVENT BEGIN:VEVENT UID:20161208T160000-craig-tracy@math.utah.edu DTSTART;TZID=America/Denver:20161208T160000 DTEND;TZID=America/Denver:20161208T170000 DTSTAMP:20260821T120902Z SUMMARY:Integrable Probability and the Role of Painlevé Functions DESCRIPTION:Speaker: Craig Tracy\, UC Davis\n\nTBA LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2016-fall/ END:VEVENT BEGIN:VEVENT UID:20161213T160000-jun-allard@math.utah.edu DTSTART;TZID=America/Denver:20161213T160000 DTEND;TZID=America/Denver:20161213T170000 DTSTAMP:20260821T120902Z SUMMARY:A non-local Maxwell condition for mechano-chemical traveling waves in cells DESCRIPTION:Speaker: Jun Allard\, UC Irvine\n\nTraveling waves appear throughout biology and are often driven by local spatial coupling, e.g., diffusion. The past ten years have revealed traveling waves in cells. These waves can be pulses of biochemical factors (diffusing proteins or metabolites) and also mechanical factors (such as the cell … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2016-fall/ END:VEVENT END:VCALENDAR
