Final Program and Abstracts
Sponsored by the SIAM Activity Group on Algebraic Geometry The purpose of the SIAM Activity Group in Algebraic Geometry is to bring together researchers who use algebraic geometry in industrial and applied mathematics. “Algebraic geometry” is interpreted broadly to include at least: algebraic geometry, commutative algebra, noncommutative algebra, symbolic and numeric computation, algebraic and geometric combinatorics, representation theory, and algebraic topology. These methods have already seen applications in: biology, coding theory, cryptography, combustion, computational geometry, computer graphics, quantum computing, control theory, geometric design, complexity theory, machine learning, nonlinear partial differential equations, optimization, robotics, and statistics.
We welcome participation from both theoretical mathematical areas and application areas not on this list which fall under this broadly interpreted notion of algebraic geometry and its applications.

Simulation, Optimization, and Identification in Solid Mechanics
August 4—August 15, 2014 Linz, Austria
The fifth Gene Golub SIAM Summer School, with a focus on solid mechanics, will take place at the Johann Radon Institute for Computational and Applied Mathematics (RICAM), located at the Johannes Kepler University in Linz, Austria. This summer school will foster advanced knowledge for the participating graduate students in several areas related to simulated materials in solid mechanics. Within this broad field the summer school will concentrate on four key issues, namely • identification of material parameters from measurements • material- and topology-optimization • optimization subject to variational inequalities • adaptive discretization The first two topics will provide a platform for in-depth discussions on the relation of the areas of identification and optimization. The third topic will augment the first two by providing insight into the behavior of those problems for which variational inequalities are required for the modeling of the materials. Finally, the summer school will look at adaptive discretization of optimization problems for the purpose of reducing the computational costs involved in the solution of the problems encountered in the first three key topics. The primary lecturers for these courses will be: • Roland Herzog, TU Chemnitz, Germany • Esther Klann, JKU Linz, Austria • Michael Stingl, FAU Erlangen-Nürnberg, Germany • Winnifried Wollner, University of Hamburg, Germany Applicants selected to participate pay no registration. Funding for local accommodations and meal expenses will be available for all participants. Limited travel funds are also available. Application deadline: February 1, 2014 For more details on the courses and on how to apply, go to:
