Alex Hening, Department of Mathematics, Tufts Universy The competitive exclusion principle in stochastic environments The competitive exclusion principle states in its simplest form that a number of species competing for a smaller number of resources cannot coexist. Nevertheless, in nature there are many instances where this is not true. One...

Vrushali Bokil, Department of Mathematics, Oregon State University Compatible Discretizations for Maxwell’s Equations in Complex Materials In this talk, we discuss the construction of a specific compatible discretization, the Mimetic Finite Difference (MFD) method, for time domain electromagnetic wave propagation in linear dispersive media. The discretization utilizes an optimization procedure...

William J. Layton, Department of Mathematics, University of Pittsburgh 5 ideas, good and bad, in computational fluid dynamics The goal of numerical analysis of the Navier-Stokes equations is to extend the accuracy, reliability and predictive ability of numerical simulations of fluid motion. This extension means improving the complexity (space, computational...

James Sethian; Department of Mathematics; University of California, Berkeley Advances in Advancing Interfaces: The Mathematics of Manufacturing of Industrial Foams, Fluidic Devices, and Automobile Painting How do inkjet printers work? What are the dynamics of a dripping faucet? How are foams mixed, bicycle helmets manufactured, and cars painted? Complex dynamics...

Aleksandar Donev, Professor of Mathematics, Courant Institute of Mathematical Sciences, New York University Numerical Methods for Inextensible Slender Fibers in Stokes Flow Every animal cell is filled with a cytoskeleton, a dynamic gel made of inextensible fibers, such as microtubules, actin fibers, and intermediate filaments, all suspended in a viscous...

Bernard Deconinck, Professor and Chair of Applied Mathematics, University of Washington Pole dynamics of solutions of integrable equations Kruskal (1974) suggested that the dynamics of solutions of the KdV equation could be understood by examining how their pole singularities (complex x, real t) interact. I will review a biased history...

Philippe Naveau, Laboratoire des Sciences du Climat et de l'Environnement, IPSL-CNRS, France Detecting changes in multivariate extremes from climatological time series Joint work with Sebastian Engelke (Geneva University) and Chen Zhou (Erasmus University Rotterdam) Many effects of climate change seem to be reflected not in the mean temperatures, precipitation or...
