The aim of the workshop is to bring together scientists working in the area of delay differential equations (DDEs) to share ideas, discuss future research directions and give presentations on current research topics. The workshop will include talks on the underlying theory, numerical methods and applications from the worlds leading experts, as well as talks on a more introductory level for participants unfamiliar with the area. The workshop will also include a short training session on numerical continuation methods for DDEs aimed at PhD students and post-docs. The workshop is organised by the Bristol Centre for Applied Nonlinear Mathematics. The workshop will be organised by the Bristol Centre for Applied Nonlinear Mathematics and will be funded by the UK EPSRC (Engineering and Physical Research Council). On Wednesday 9th September 2009, there will be a series of tutorial sessions on numerical bifurcation methods and software for analysis of the delay differential equations.

The purpose of this workshop is to bring together academic and industrial researchers from all over the world so that they can exchange ideas concerning the physical and numerical modeling of multiphase flows, with an emphasis on real problems of industrial nature. More information on this event as well as on the Call for Papers can be found at http://cargesemtl2009.mathappl.polymtl.ca/ We would appreciate if you could forward this e-mail to anyone who may be interested by this workshop.

The workshop is part of the Priority Program 1324 of the German Research Foundation (DFG), see http://www.dfg-spp1324.de/, and organized by Stephan Dahlke, Marburg Stig Larsson, Goteborg Klaus Ritter, Darmstadt Rene Schilling, Dresden Wilhelm Stannat, Darmstadt Jerzey Zabczyk, Warsaw We believe that the modelling of SPDEs and their applications in various fields, including numerical approximation, is currently a fast growing area of research activities. We are convinced that a workshop that is focussed on these aspects will provide a great opportunity to start new scientific collaborations among participants from possibly different areas having SPDEs as their common scientific interest. As a main feature of our workshop there will be short courses devoted to the topics modelling (Karniadakis), analysis (Roeckner), and numerics (Gyoengy).
