Multimodel and Multialgorithm Coupling for Multiscale Problems

July 4 - 7, 2011
Snowbird, Utah, USA

This 2011 von Neumann Symposium on Multimodel and Multialgorithm Coupling for Multiscale Problems is organized by John B. Bell (chair), Lawrence Berkeley National Laboratory; Alejandro L. Garcia, San Jose State University; and Francis Alexander, Los Alamos National Laboratory, and will take place at Snowbird Resort, Snowbird, Utah, July 4-7, 2011. View poster here.

The topic was selected by the AMS von Neumann Symposium Committee, whose members at the time were Ronald A. DeVore, Texas A&M University; James A. Sethian, University of California, Berkeley; and Joel H. Spencer, New York University-Courant Institute.

This symposium is supported with a fund established by Dr. and Mrs. Carrol V. Newsom in honor of the memory of John von Neumann.

Background

Many important applications in both science and technology are characterized by having interactions among various phenomena or components with dissimilar structures and occurring over a broad range of length and time scales. These classes of problems require innovative approaches targeted at spanning a large range of scales and, in this regard, multimodel and multialgorithm methods have emerged as promising new directions. A defining characteristic of these approaches is that rather than using a single formulation for a problem, they utilize multiple models and algorithms, each appropriate to a particular scale. Multimodel and multialgorithm methods are powerful tools; however the mathematical and numerical analysis required for successfully combining models or coupling algorithms can be as complicated as the analysis of the individual models and algorithms themselves. By their nature, multiscale problems are highly interdisciplinary so multimodel and multialgorithm methods have recently started arising in a variety of contexts and disciplines. The goal of the symposium is to enable applied mathematicians and scientists from a variety of application areas to discuss current practices and future research directions in the development of hybrid methodologies for multiscale phenomena. In addition, by bringing together the mathematics community with applications specialists, we hope to identify some of the key mathematical ideas that transcend particular applications. Overall, the symposium should serve as a focal point for assessing the state of the art and articulating important future research directions.

The symposium will be organized around eight plenary talks given by Aleksandar Donev, Courant Institute, New York University; Weinan E, Princeton University; Nicolas Hadjiconstantinou, Massachusetts Institute of Technology; George Karniadakis, Brown University; Rupert Klein, Freie Universität, Berlin; Petros Koumoutsakos, ETH Zurich; J. Tinsley Oden, The University of Texas at Austin; and George Oster, University of California, Berkeley. There will also be a series of shorter presentations.

The participation of women, underrepresented minorities, junior scientists (advanced graduate students and recent Ph.D.s), as well as industry and national laboratory representatives are especially encouraged.
