Due to the tight schedule of lectures given by our invited speakers we cannot offer time for a short communication to all the other participants. Nevertheless, if you would like to communicate your latest results at the meeting, you are kindly invited to present a poster at the meeting. The posters will then be located in or in close vicinity to the room where the coffee break will take place, and we hope that also in this way your results will find enough attention. Format: Although it will be up to you how you would like to design your poster we would like to recommend a format of 4 sheets of A4. In this case the content of the poster will be similar to an extended abstract. One is able to present the main results of a paper, might give a couple of references, and some hints for the proof. This is more or less the limit one is able to read in a couple of minutes. Graphics, diagrams (especially pictures) and displayed equations are certainly attracting the eye of the potential reader. In any format please make sure that the written text is easily readable (14pt letters and a sufficient lineskip).
