One is arithemetic: any degree n extension field K of k can be embedded in nxn matrices, in a way canonical up to conjugacy. In terms of linear algebra, the corresponding matrices have their eigenvalues in K. For this reason, … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2004-fall/ END:VEVENT BEGIN:VEVENT UID:20041001T160000-speaker@math.utah.edu DTSTART;TZID=America/Denver:20041001T160000 DTEND;TZID=America/Denver:20041001T170000 DTSTAMP:20260821T120902Z SUMMARY:Arthur Packets and Unitary Representations DESCRIPTION:Speaker: speaker\n\nArchival event entry migrated from the legacy colloquium website.

A family of filters with different … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2004-fall/ END:VEVENT BEGIN:VEVENT UID:20041028T160000-speaker@math.utah.edu DTSTART;TZID=America/Denver:20041028T160000 DTEND;TZID=America/Denver:20041028T170000 DTSTAMP:20260821T120902Z SUMMARY:Non-positively Curved Cubical Complexes in Group Theory DESCRIPTION:Speaker: speaker\n\nWe will discuss non-positively curved cubical complexes and their relationship to various topics in geometric group theory.

The next Monday, Southwest Research Institute was contacted about performing tests (and later analysis) to determine the plausibility of a foam impact on the left wing being the cause of the loss of the vehicle.

As q varies these cohomology groups interpolate between ordinary cohomology and cohomology with compact supports. Although these groups are Hilbert spaces (usually … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2004-fall/ END:VEVENT BEGIN:VEVENT UID:20041118T160000-speaker@math.utah.edu DTSTART;TZID=America/Denver:20041118T160000 DTEND;TZID=America/Denver:20041118T170000 DTSTAMP:20260821T120902Z SUMMARY:Locomotion by Destabilizing Symmetries DESCRIPTION:Speaker: speaker\n\nRecent experiments in the Courant Institute Applied Math Lab have shown fascinating and subtle interactions between fluids and bodies moving through them, and have suggested that fluidic response to body motions can change dramatically with the "forcing Reynolds number," and can result in body … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2004-fall/ END:VEVENT BEGIN:VEVENT UID:20041202T160000-speaker@math.utah.edu DTSTART;TZID=America/Denver:20041202T160000 DTEND;TZID=America/Denver:20041202T170000 DTSTAMP:20260821T120902Z SUMMARY:Irreducible Hyperfinite II 1 Subfactors DESCRIPTION:Speaker: speaker\n\nThe goal of this talk is to present a new noncommutative tool in the study of the subfactor theory. The theory of von Neumann algebras was introduced by Murray and von Neumann as the mathematical foundation of quantum mechanics. Every von Neumann algebra can be decomposed as a direct "sum" of … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2004-fall/ END:VEVENT END:VCALENDAR
