What is not so obvious is that in order for the solution to be $C^\infty$, the BC and IC … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2006-spring/ END:VEVENT BEGIN:VEVENT UID:20060119T160000-kartik-prasanna@math.utah.edu DTSTART;TZID=America/Denver:20060119T160000 DTEND;TZID=America/Denver:20060119T170000 DTSTAMP:20260821T120902Z SUMMARY:Elliptic curves, quadratic twists and L-values DESCRIPTION:Speaker: Kartik Prasanna\, UCLA\n\nThe first half of the talk will be an elementary discussion of elliptic curves, their associated L-functions and the structure of the Birch and Swinnerton-Dyer conjecture (BSD) for the behaviour of such L-functions at the central point s=1. In the second half, I will begin by explaining a theorem of … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2006-spring/ END:VEVENT BEGIN:VEVENT UID:20060202T160000-sai-kee-yeung@math.utah.edu DTSTART;TZID=America/Denver:20060202T160000 DTEND;TZID=America/Denver:20060202T170000 DTSTAMP:20260821T120902Z SUMMARY:Classification and construction of fake projective planes DESCRIPTION:Speaker: Sai Kee Yeung\, Purdue University\n\nFake projective planes are smooth complex surfaces different from the complex projective plane but has the same Betti numbers as the latter. The first example was constructed by Mumford at late seventies using p-adic uniformization and two more were constructed more recently by Ishida-Kato by … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2006-spring/ END:VEVENT BEGIN:VEVENT UID:20060207T160000-y.-c.-yen-ching-pao@math.utah.edu DTSTART;TZID=America/Denver:20060207T160000 DTEND;TZID=America/Denver:20060207T170000 DTSTAMP:20260821T120902Z SUMMARY:Mathematical Models for Assessing the Passive Elasticity and Active Contractility of Heart Muscles DESCRIPTION:Speaker: Y.

In particular, the accurate reconstruction of a continuous motion signal is necessary for the control of devices such as computer cursors, robots, or a patient's own paralyzed limbs.

We then explain what is known at this point, and which part of the conjecture remains open.

A familiar example is the one--dimensional Allen Cahn equation: initial data is drawn quickly to a ``multi--kink'' state and … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2006-spring/ END:VEVENT BEGIN:VEVENT UID:20060222T160000-michael-westdickenberg@math.utah.edu DTSTART;TZID=America/Denver:20060222T160000 DTEND;TZID=America/Denver:20060222T170000 DTSTAMP:20260821T120902Z SUMMARY:The Entropy Condition for Hyperbolic Conservation Laws DESCRIPTION:Speaker: Michael Westdickenberg\, Bonn Univ.\n\nSince weak solutions of hyperbolic conservation laws may be nonunique, typically an entropy condition is imposed in order to obtain uniqueness. We discuss how the entropy condition implies regularity and structure of solutions of scalar conservation laws.

During the first part of the talk, I will try to place this problem in a wider historical context, and emphasize how a hidden symmetry can be exploited to find arithmetic formulae.

For example, it is still not known if there are infinitely many primes of the form n^2 + 1. There is a long history of analogies between the integers and polynomials … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2006-spring/ END:VEVENT BEGIN:VEVENT UID:20060307T160000-speaker@math.utah.edu DTSTART;TZID=America/Denver:20060307T160000 DTEND;TZID=America/Denver:20060307T170000 DTSTAMP:20260821T120902Z SUMMARY:Note: This colloquium will be held in LCB 215.

A distinctive aspect of the theory is that it requires an additional boundary condition, or condition across any interface.
