20042005 Program
See http://www.ima.umn.edu/matter for a full description of the
20042005 program on
Mathematics of Materials and Macromolecules: Multiple Scales, Disorder, and Singularities
and http://www.ima.umn.edu/schedule for schedule updates.
Our thanks to outgoing Board members Dimitris Bertsimas (MIT), Richard D. James (University of Minnesota), James Sethian (University of California, Berkeley), and De Witt Sumners (Florida State University) for all their help. Special thanks to De Witt Sumners for his service as Board chair.
This winter the IMA will offer two tutorial/workshops geared towards scientists interested in industrial applications of mathematics. Composites: Where Mathematics Meets Industry, February 7–9, is organized by Graeme Milton. It will include lectures on modeling the pipeline of high performance, nanocomposite materials and effective properties (Greg Forest), estimating the properties of composites and smart materials (Graeme Milton) and nanoparticle suspensions with giant electrorheological response (Ping Sheng), problem presentations by industrial scientists, and discussion groups. New Paradigms in Computation, March 28–30, is organized by Robert Kohn and will include lectures on fast multipole methods (Leslie Greengard), level set methods (James Sethian), and multiscale computation (Weinan E).
The winter lectures in the IMA public lecture series Math Matters will be given on the final evenings of the tutorial/workshops. On February 9, David Baraff will present Math Behind the Curtains: Dynamic Simulation at Pixar Animation Studios. On March 30, Thomas Hales will present Computers and the Future of Mathematical Proof.

Shi Jin (University of Wisconsin)  Computation of Multivalued Solutions of Nonlinear PDEs 
Abstract: Many physical problems arising from high frequency waves, dispersive waves or Hamiltonian systems require the computations of multivalued solutions which cannot be described by the viscosity methods. In this talk I will review several recent numerical methods for such problems, including the moment methods, kinetic equations and a level set method. Applications to the semiclassical Schroedinger equation and EulerPoisson equations, with applications to modulated electron beams in Klystrons, will be discussed.  
Adrian Lew (Stanford University)  Modeling and simulation of materials under highly dynamic loads 
Abstract: The simulation of the mechanical response of materials has been the task of computational mechanics since its inception. Only now, however, can we seriously envision reliable and accurate simulations for materials undergoing highly dynamic loads, such as those generated by impacts, blast and detonation of energetic materials. In this talk I will describe some key algorithmic developments to enable virtual material testing. I will present a class of timeintegration algorithms termed Asynchronous Variational Integrators (AVI), designed to accelerate the simulation of multiphysics problems with multiple time scales, and discuss a predictive, multiscale material model for shockinduced martensitic phase transitions in iron.  
Daniel Spirn (University of Minnesota)  Schrodinger Vortices II 
Abstract: Under the limit of large GinzburgLandau parameter, Schrodinger vortices condense down to point particles and satisfy a simple Kirchhoff's Law  just like Euler point vortices. Given some technical variational results, I will describe the proof of vortex dynamics for the SchrodingerGinzburgLandau equations. (This talk is a continuation of the December 8 lecture.)  
Peter Takac (Universitaet Rostock)  Elliptic and Parabolic Spectral Problems with the pLaplacian 
Abstract: We treat a canonical spectral problem for the Dirichlet pLaplacian near the first eigenvalue. We give a precise asymptotic formula for large solutions of the spectral problem corresponding to the Fredholm alternative, thus obtaining a priori under various conditions.
