This has given us new insights and results concerning modular representations, and has also lead to unexpected results in commutative algebra.

Modeling is an essential tool to better understand their behavior. Based on experimental data, we introduce some recent models which aim to explain such dynamics. … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2013-spring/ END:VEVENT BEGIN:VEVENT UID:20130214T160000-jun-allard@math.utah.edu DTSTART;TZID=America/Denver:20130214T160000 DTEND;TZID=America/Denver:20130214T170000 DTSTAMP:20260821T120902Z SUMMARY:Traveling waves in crawling cells DESCRIPTION:Speaker: Jun Allard\, University of California, Davis\n\nCrawling cells, including the white blood cells that patrol your body in search of infections, display several distinct dynamical patterns driven by both biochemistry (diffusion and reactions between chemical species) and mechanics (physical forces between the components inside cells).

In addition, ocean circulation models can be used to drive transport models of, e.g., hydrocarbons in the coastal environment.

This can be beneficial to some fish, since the plankton they eat depends on a well-stirred medium to feed on nutrients. Bacterial colonies also stir their environment, and this is even more crucial for them … LOCATION:JWB 335 URL:http://math.utah.edu/research/colloquia/test/2013-spring/ END:VEVENT BEGIN:VEVENT UID:20130404T160000-lisa-fauci@math.utah.edu DTSTART;TZID=America/Denver:20130404T160000 DTEND;TZID=America/Denver:20130404T170000 DTSTAMP:20260821T120902Z SUMMARY:A Tale of Waving Tails: Calcium-Driven Dynamics of Undulatory Swimmers DESCRIPTION:Speaker: Lisa Fauci\, Tulane University\n\nLocomotion due to body undulations is observed across the entire spectrum of swimming organisms, from microorganisms to fish. The internal force generating mechanisms range from the action of dynein molecular motors within a mammalian sperm to muscle activation in lamprey.

DESCRIPTION:Speaker: Mark Andrea de Cataldo\, State University of New York, Stony Brook\n\nIn this talk, which is aimed at non-experts, I will introduce two moduli spaces of structures on a compact Riemann surface, relate them via a result called non-abelian Hodge theorem, and then discuss a recently observed and somewhat mysterious symmetry relating their cohomology rings.
