WIAS Conferences, Colloquiums, and Workshops

KOLLOQUIUM DES SCHWERPUNKTPROGRAMMS ,,INTERAGIERENDE STOCHASTISCHE SYSTEME VON HOHER KOMPLEXITÄT`` (Colloquium of the DFG Priority Program ``Interacting stochastic systems of high complexity'')

Berlin, January 7-9

Organized by: WIAS (FG 5), DFG Priority Program, Technische Universität Berlin and Universität Erlangen

Sponsored by: DFG

At the beginning of the year, the annual colloquium of the DFG Priority Program ``Interacting stochastic systems of high complexity'' took place at WIAS with the aim to present, in 12 talks, selected results of the participating groups. The agenda was completed by three talks by foreign guests (E. Bolthausen, M. Keane and C. Maes). As in the past years, the colloquium was a success and contributed largely to the networking of the scientists collaborating on different subsections of stochastics in the program. High-quality talks of younger collaborators proved the program's worth in the field of the promotion of young scientists.


Berlin, September 19-21

Organized by: WIAS (FG 1, FG 3, FG 7)

Sponsored by: WIAS, DFG

The workshop ``Multiscale Problems in Quantum and Classical Mechanics, Averaging Techniques and Young Measures'' has been organized by H.-Chr. Kaiser (FG 1) and Th. Koprucki (FG 3) in cooperation with W. Dreyer (FG 7) and A. Mielke (Stuttgart). It is the second event in a series of new workshops within the DFG Priority Program ``Analysis, Modeling and Multiscale Problems'', initiated by the meeting ``Multiscale Problems in Quantum Mechanics and Averaging Techniques'' held in Konstanz on October 25-26, 2001 (organizers: A. Jüngel (Konstanz) and A. Arnold (Saarbrücken)).

The general aim of this workshop was to foster joint activities within the priority program. The topics were many-particle systems, electronic structure calculation, quantum-classical coupling, semiconductor device simulation, semiconductor nanostructures, quantum hydrodynamics, time averages and Young measures, adiabatic and scaling limits, surface nanostructures, multiscale problems of the atomic chain, evolution of Young measures, wavelets, homogenization and two-scale finite elements. The schedule was coordinated with that of another workshop within the priority program: ``Efficient Algorithms for Multiscale Dynamics'' which took place on September 23-25, 2002, at the Freie Universität Berlin (organizers: M. Dellnitz (Paderborn), W. Huisinga (Berlin), Ch. Lubich (Tübingen), Ch. Schütte (Berlin)). Five participants attended both workshops.


Berlin, October 2-5

Organized by: WIAS (FG 3)

Sponsored by: COMPAQ, DFG, WIAS

The main focus of this conference was on the problem class of nonlinear transport/diffusion/reaction systems, chief amongst these being: the Navier-Stokes equations, porous media-flow problems.

The purpose of the conference was to draw together researchers working in the fields of scientific computing, numerical analysis and modeling with a common interest in the numerical treatment and the computational solution of systems of nonlinear partial differential equations arising from applications of physical problems in science and engineering.

Themes included: finite element methods, treatment of incompressible flow problems, numerical simulations of free surface flows, geometric and algebraic multigrid methods, transport processes in porous media, image processing.

Of particular interest were those contributions which emphasize unsolved problems, challenging open questions from applications and assessing the various numerical methods used to handle them, instead of concentrating on accurate results from ``solved'' problems.

There were 54 participants including 31 invited speakers.

Some of the contributions will be published in ``Lecture Notes in Computational Sciences and Engineering''.

Berlin, November 18-19

Organized by: WIAS (FG 2), GAMM, SFB 555

Sponsored by: WIAS, DFG (SFB 555)

The workshop has been organized by GAMM (Gesellschaft für Angewandte Mathematik und Mechanik (society for applied mathematics and mechanics)) and SFB 555 (DFG Collaborative Research Center ``Complex non-linear processes''). It met with a good response (54 participants from 5 countries). It focused on modern approaches for controling complex processes (pattern formation, synchronization) and its application (process engineering, robotics, vehicle dynamics).

WORKSHOP ``COMPOSITE FORSCHUNG IN DER MECHANIK'' (Composite research in mechanics)

Berlin, November 18-20

Organized by: WIAS (FG 7), Technische Universität (TU) Berlin

Sponsored by: WIAS, TU Berlin

The category of composite materials consists of classical composites, like fibre-reinforced substances, patched metallic contacts, silicon carbide laminates as well as nonclassical composites like multiphase bodies. Both composite classes have been discussed in this workshop, with the special focus on problems resulting from industrial purposes.

The talks stressed in particular problems within the areas of elasto-plasto mechanics, mechanisms for failure and lifetime calculations, energy release rates related to the evolution of cracks and phase transitions within the framework of phase-field models.


Berlin, November 28

Organized by: WIAS (FG 2), SFB 555

Sponsored by: WIAS, Humboldt University of Berlin

The minisymposium has been organized by SFB 555 (DFG Collaborative Research Center ``Complex non-linear processes''). It attracted more than 20 people from different research institutes in Berlin. It focused on high frequency self-pulsations of multi-section semiconductor lasers: modeling, simulation, experiments. The talks initiated an intensive scientific discussion.
