First I will discuss the development of new tools for understanding the spatio-temporal dynamics of complex biochemical networks. Currently there is an extensive toolbox for mapping and understanding the … LOCATION:LCB 219 URL:http://math.utah.edu/research/colloquia/test/2014-spring/ END:VEVENT BEGIN:VEVENT UID:20140204T160000-ting-zhou@math.utah.edu DTSTART;TZID=America/Denver:20140204T160000 DTEND;TZID=America/Denver:20140204T170000 DTSTAMP:20260909T174830Z SUMMARY:Quantitative thermo-acoustic tomography (TAT) DESCRIPTION:Speaker: Ting Zhou\, Massachusetts Institute of Technology\n\nTAT is an example of a coupled-physics modality, which combines the high contrast of a physical phenomenon (here the electrical properties of tissues) with the high resolution of another phenomenon (here ultrasound). Thermo-acoustic imaging may be decomposed into two steps. The first step aims at … LOCATION:LCB 219 URL:http://math.utah.edu/research/colloquia/test/2014-spring/ END:VEVENT BEGIN:VEVENT UID:20140206T160000-braxton-osting@math.utah.edu DTSTART;TZID=America/Denver:20140206T160000 DTEND;TZID=America/Denver:20140206T170000 DTSTAMP:20260909T174830Z SUMMARY:Geometric methods for graph partitioning DESCRIPTION:Speaker: Braxton Osting\, Univeristy of California, Los Angeles\n\nSeveral geometric methods for graph partitioning have been introduced in the past few years, with wide applications in clustering, community detection, and image analysis. These methods, which I'll review, are built on graph-based analogues of total variation, motion by mean curvature, the … LOCATION:LCB 219 URL:http://math.utah.edu/research/colloquia/test/2014-spring/ END:VEVENT BEGIN:VEVENT UID:20140213T160000-karl-schwede@math.utah.edu DTSTART;TZID=America/Denver:20140213T160000 DTEND;TZID=America/Denver:20140213T170000 DTSTAMP:20260909T174830Z SUMMARY:Singularities of polynomials -- multiplier ideals, test ideals and alterations DESCRIPTION:Speaker: Karl Schwede\, Pennsylvania State University\n\nWe will consider solution sets to polynomial equations. For example, consider y^2 = x^3, the solution set has a singularity at the origin (a cusp). I will talk about different ways to measure singularities such as this one. First I will discuss the multiplier ideal, a way to measure singularities … LOCATION:LCB 219 URL:http://math.utah.edu/research/colloquia/test/2014-spring/ END:VEVENT BEGIN:VEVENT UID:20140320T160000-timo-sepp%C3%A4l%C3%A4inen@math.utah.edu DTSTART;TZID=America/Denver:20140320T160000 DTEND;TZID=America/Denver:20140320T170000 DTSTAMP:20260909T174830Z SUMMARY:Variational formulas for directed paths in a random medium DESCRIPTION:Speaker: Timo Seppäläinen\, University of Wisconsin-Madison\n\nThis talk begins with a reminder of classic random walk and then proceeds to models of random paths currently studied in probability and statistical mechanics. In particular, we discuss directed percolation and directed polymer models. Subadditive ergodic theory gives deterministic large scale … LOCATION:LCB 219 URL:http://math.utah.edu/research/colloquia/test/2014-spring/ END:VEVENT BEGIN:VEVENT UID:20140327T160000-john-brady@math.utah.edu DTSTART;TZID=America/Denver:20140327T160000 DTEND;TZID=America/Denver:20140327T170000 DTSTAMP:20260909T174830Z SUMMARY:The Micromechanics of Colloidal Dispersions DESCRIPTION:Speaker: John Brady\, California Institute of Technology\n\nWhat do corn starch, swimming spermatozoa, DNA and self-assembling nanoparticles have in common? They are all (or can be modeled as) ‘particles’ dispersed in a continuum suspending fluid where hydrodynamic interactions compete with thermal (Brownian) and interparticle forces to set structure and … LOCATION:LCB 219 URL:http://math.utah.edu/research/colloquia/test/2014-spring/ END:VEVENT BEGIN:VEVENT UID:20140403T160000-mitchell-luskin@math.utah.edu DTSTART;TZID=America/Denver:20140403T160000 DTEND;TZID=America/Denver:20140403T170000 DTSTAMP:20260909T174830Z SUMMARY:Mathematical Foundations for Multiscale Materials Modeling and Computing DESCRIPTION:Speaker: Mitchell Luskin\, University of Minnesota\n\nPredictive computational models for materials must include the interactions of multiple spatial and temporal scales. These scales can be classified as microscopic, mesoscopic, and macroscopic for simplicity, but there are typically structures at many scales with varying degrees of separation.

Cantor sets arise in many areas; in this talk we will discuss their relevance in the spectral theory of Schröodinger operators. We discuss several results showing that the spectrum of such an operator is a … LOCATION:LCB 219 URL:http://math.utah.edu/research/colloquia/test/2014-spring/ END:VEVENT BEGIN:VEVENT UID:20140415T160000-martin-bridson@math.utah.edu DTSTART;TZID=America/Denver:20140415T160000 DTEND;TZID=America/Denver:20140415T170000 DTSTAMP:20260909T174830Z SUMMARY:Capturing infinite groups by their finite quotients DESCRIPTION:Speaker: Martin Bridson\, Oxford University\n\nThere are many situations in geometry and group theory where it is natural or convenient to study infinite groups via their finite quotients and finite-index groups. If a group G is residually finite (ie every element survives in some finite quotient) then one might hope to recover a lot of … LOCATION:LCB 219 URL:http://math.utah.edu/research/colloquia/test/2014-spring/ END:VEVENT END:VCALENDAR
