Alcala de Henares (Madrid), Spain. First Announcement. Call for Papers. The conference will feature recent advances in mathematical ecology, using new but also classical approaches, in a variety of topics including (but not limited to) the following: population ecology, behavioral ecology, ecotoxicology, evolutionary dynamics, management of living resources, population grouping, spatial aspects of ecology, stochastic models in ecology, individual based models, multiple scaling, etc.. Proposals for organizing sessions on these topics or other related ones are encouraged. Deadline for Session Proposals: December 1, 2002 Deadline for Abstracts: May 1, 2003 All information can be found on the WWW-server: http://www2.uah.es/matema/Aicme/aicme.htm ------ Subject: Call for "outline" Programme proposals of the ESF From: "Marie Gruber" Date: Mon, 9 Sep 2002 06:55:22 +0200 The ESF Standing Committee for the Physical and Engineering Sciences (PESC) herewith launches (9 September 2002) a call for "outline" proposals for ESF Scientific Programmes. PESC wishes proposals to address NOVEL SCIENCE in one or more of the following fields: chemistry, physics, mathematics, information sciences and technology, fundamental engineering sciences, materials sciences and engineering. Multi-disciplinary proposals based in these areas but also involving fields within the remit of other ESF Standing Committees are also welcome. An ESF Scientific Programme is a networking activity, bringing together key researchers and research groups for four or five years to address a major scientific issue at the European level. Key objectives are to bring synergy and European added value to research work being undertaken at the national level, and to achieve a visible impact at the European level to the advantage of European science. ESF Programmes are financed on an a-la-carte basis by ESF Member Organisations (national research councils for the most part) which decide to contribute (there is no obligation on them to do so). The launching of an ESF Programme is dependent on sufficient financial support having been obtained from Member Organisations. Following peer review, approx. 10 outline proposals are expected to be selected in the 1st stage. The proposers of these will be invited, early in February 2003, to submit a full proposal. From these full proposals, the Committee will, following further peer review, recommend approx. 4 proposals to ESF Member Organisations for launching early in 2004. The deadline for submission of proposals is 31 October 2002. Further details, including a section on the "application procedure", are available at http://www.esf.org/esf_article.php?domain=1&activity=5& article=262&page=794&chapter=0 ------ Subject: A PhD position in Groningen From: "H.W.Broer" Date: Thu, 12 Sep 2002 10:43:42 +0200 Vacancy: PhD Research position for the project Dynamics and Geometry of Resonant Bifurcations Institute of Mathematics and Computing Science University of Groningen Topics of research Our recent work in the theory of resonant interaction between several oscillators touches upon certain new aspects of resonant bifurcations, in particular their complexity in the form of `instability pockets'. In this work, equivariant singularity theory plays a prominent role. Our study of these phenomena mainly focuses on certain parameter space aspects, but a satisfactory understanding both of the global (higher dimensional) geometry and of the corresponding dynamics still largely is lacking. This Phd research project aims at picking up this challenge. Rather sophisticated tools from bifurcation-- and singularity theory are needed and partly have to be developed. On the one hand we expect that for the singularity theory we need to use and partly develop tools from computer algebra. On the other hand for properly understanding the geometry of bifurcation- and catastrophe sets in higher dimensional spaces one needs to visualize suitably chosen cross-sections. Here we will be using visualization techniques.

In this period the person appointed has to prepare and defend a PhD thesis. The position is funded by the Netherlands Organization for Scientific Research (NWO). It is embedded in the research group Dynamical Systems. Supervisors will be Prof.Dr. H.W. Broer and Dr. G. Vegter. Your qualifications You are a university graduate (at the Diploma or Master of Science level) in Mathematics or Physics. You are expected to have an excellent academic record (list of examination marks from your university study) and to be interested in research in Dynamical Systems. You should be able to write scientific articles and reports (to be proven by your graduation thesis or another comparable report) and be fluent in English. How to apply Send your application, including a CV and a description of your ideas for research in the specified area to Prof. Dr. H.W. Broer (broer@math.rug.nl). The position will be open until a suitable candidate is found. Applicants are also requested to ask that two letters of recommendation be sent to this address. ------ From: M.
