Dear Colleague,

 We would like to invite you to participate in a research workshop entitled: "Coping with Complexity:  Model Reduction and Data Analysis" in conjunction with the 6th Conference on Algorithms for Approximation” that will be held in Ambleside, Lake District, UK from August 31 to September 4, 2009. The theme of the workshop is deliberately broad in scope and aims at promoting an informal exchange of new ideas and fresh methodological perspectives in the increasingly important, inherently interdisciplinary areas of model reduction, data analysis, approximation and visualization in the presence of complexity.  The goal of this initiative is to assemble a group of people with a wide variety of expertise reflecting the thematically interdisciplinary nature of the workshop, to organize a series of presentations and to encourage fruitful discussions in an informal and casual format, thus circumventing some of the “language barriers” often unnecessarily experienced by researchers representing different disciplines.


The broad thematic structure of the workshop is organized around the following list of topics:


1)      Theoretical Approaches (deterministic and stochastic): Invariant manifolds, inertial manifolds, perturbation theory, approximation theory, normal form theory


2)      Computational and Algorithmic Approaches: Legacy codes and timesteppers, numerical computation of invariant manifolds, invariant grids, coarse-graining approaches


3)      Data analysis and approximation techniques: Principal manifolds, dimension reduction methods, data visualization approaches and their applications.


4) Fields of Applications: Non-equilibrium statistical mechanics, kinetic theory, hydrodynamics and mechanics of continuous media, (bio)chemical kinetics, bioinformatics, particulate systems, nonlinear dynamics, nonlinear control, .

We believe that your presence and contribution would significantly enhance the quality of the workshop and enable the realization of its main objectives.

The workshop activities will involve 30min presentations in thematically similar areas organized in sessions, open discussions on new developments and promising interdisciplinary research directions, as well as informal social activities.

 At this stage we would like to invite you to submit a title and brief abstract of your talk by March 30th, 2008 (please send an e-mail to the special workshop address or to Professor Alexander Gorban at:

Furthermore, participants are invited to submit full papers of their contributions by November 30th 2009 to be included into a Proceedings Volume, that can form the basis of a series of peer-reviewed papers published in a Special Issue of a reputable journal or a Special Volume prepared in conjunction with a well known publisher. Furthermore, interested participants should feel free to contribute to a "notebook of open problems" that is going to be included into the Proceedings volume as well, by preparing a problem statement, underscoring its significance and putting it into a broader methodological perspective.

The workshop's program, as well as other practical details and arrangements with respect to your trip to Ambleside, Lake District will be sent to you as soon as the workshop's organizational plan attains its final form.

Please do not hesitate to call us at:  +44 116 223 1433 (Alexander Gorban) or contact by e-mail to the special workshop address or to .

 We are looking forward to seeing you in Ambleside.
