Summer School at the Institut d'Etudes Scientifiques de Cargese (Corsica, Fr) Morphogenesis through the interplay of nonlinear chemical instabilities and elastic active media Scientific organization P. Borckmans: Universite Libre de Bruxelles, Belgium. P. De Kepper: CRPP, Universite Bordeaux I, France. A. Khokhlov: Moscow State University, Russia. S. Metens: University Paris 7, France. Y. Osada: Hokkaido University, Japan. R.A. Siegel: University of Minnesota, USA. M. Zrinyi: Budapest University of Technology and Economics, Hungary. The aim of the School is to teach the advanced principles of gel dynamics, characterized by extensive volume variations, under the influence of a variety of stimuli, principally chemical reactions. This property has led to either existing, or promising new applications, including intelligent materials, bioMems, biological and chemical sensors, and even some military oriented items\205 . The possibility of using autocatalytic chemical reactions to introduce new autonomous properties because of emergent phenomena present in neither the gel nor the chemical dynamics separately, will also be assessed. The aim of the School is to teach both theoretical and experimental aspects, from the ground off, of the two fields that are brought into interaction. The multidisciplinary character of the subject (soft matter physics, nonlinear dynamics and continuum mechanics, \205) will offer an excellent opportunity foryoung scientists to benefit of the experience of some of the best specialists in those disciplines. Registration has to be carried out through the web page of the School : http://www.ulb.ac.be/sciences/nlpc/CARGESE/index.html For any additional information please email to metens@ccr.jussieu.fr List of Lecturers Ben Amar M., Paris, France Boudaoud A., Paris, France Boissonade J., Bordeaux, France Couder Y., Paris, France De Kepper P., Bordeaux, France Doi M., Tokyo, Japan Epstein I., Waltham, USA Gong J.P., Hokkaido, Japan Khokhlov A.

Our theme is "How does complexity science contribute to global environmental issues ?" At first sight complexity science seems a natural way to address environmental issues because it is designed to explain the properties and behaviours of systems with many interacting parts, but there are both fundamental and practical challenges in testing whether complexity theories can really explain "real world" data. Our meeting aims both to highlight the contribution that complexity theories are already making to high-priority problems in earth system science and to present them with new observational challenges. An important outcome will be increased dialogue between the earth sciences and the complexity sciences, leading to better understanding and new collaborations. The deadline for registration, booking accomodation and abstract submission is 31st May 2007. Invited speakers so far include: David Broomhead (Manchester) Armin Bunde (Giessen) Joern Davidsen (Calgary) Theo Geisel (MPI Gottingen) Juergen Kropp (Potsdam Institute) Tom Mullin (Manchester) Maya Paczuski (Calgary) Raul Sanchez (Oak Ridge) Leonard Smith (LSE/Oxford) David Thomson (Queen's University at Kingston) Geoffrey West (Santa Fe Institute) * Rich Williams (Microsoft Research) * Unconfirmed For more details, including accomodation, registration and abstract submission, please visit http://www.antarctica.ac.uk/Meetings/2007/complexity2007/ Sincerely, Mervyn Freeman and Nick Watkins (British Antarctic Survey) on behalf of the Scientific Programme Committee : Sandra Chapman (Warwick) Greg King (Warwick/Lisbon) Tim Lenton (UEA) Bill Nuttall (Cambridge) Emily Shuckburgh (BAS) ------ Subject: Workshop on time integration of evolution problems From: "Alexander Ostermann" Date: Tue, 27 Mar 2007 17:14:38 +0200 Workshop: Time integration of evolution problems September 12-15, 2007 Innsbruck, Austria The Department of Mathematics of the University of Innsbruck organizes in collaboration with the numerical analysis groups of the Universities of Trieste and Udine the fourth workshop in series on numerical analysis and scientific computing. This year, the topic will be time integration of evolution problems. The intention of the workshop is to provide a platform for exchanging new ideas and results in the development of numerical methods for evolution equations. The emphasis will be laid on the time integration of PDEs. We try to cover both, theoretical and practical aspects, and we want to bring together numerical analysts working in the field as well as PhD students who want to start in this area. If you are interested in attending the workshop, please send an e-mail to one of the local organizers (alexander.ostermann@uibk.ac.at or mechthild.thalhammer@uibk.ac.at). Please note that the number of participants is limited.

The objectives of the Workshop comprise both education and research. The goal of the educational component is to expose graduate students (from both the physical and the mathematical sciences) to several aspects of liquid crystals related to the three workshop themes. Some coverage will be given to physics background (including lab experiences), mathematical models and their analyses, and numerical methods. The main research objective is to foster a lively exchange between the participating physicists and the mathematicians on the concerned topics. The 10-day Workshop will include 8 tutorial lectures and 15 research talks (both balanced between physics and mathematics), plus 8 different laboratory experiences. In addition there will be a day for student presentations and a concluding roundtable discussion. Funding and space are available for a small number of graduate students.
