Sage days 24 @ RISC, Austria
by Burcin Erocal 26 Feb '10

26 Feb '10

Hi, Sage days 24 will take place at RISC, in Austria this summer. You can find the announcement text below. As you may know, Sage uses a variant of GiNaC called pynac [1], which replaces the numeric class to use Python objects instead of cln, as its symbolic backend. [1] http://pynac.sagemath.org/ It would be great to see GiNaC developers & users at this event. There will be plenty of occasions for discussions and coding sessions. Feel free to write to me off list with any questions. Cheers, Burcin Feel free to distribute as appropriate. Apologies for multiple copies. ************************************************************ Sage Days 24 on Differential Algebra and Special Functions July 17-22, 2010 http://wiki.sagemath.org/days24 Research Institute for Symbolic Computation, Linz, Austria ************************************************************ The objective of this workshop is to * provide a gentle introduction to Sage (installation, features, tutorials on basic usage and development), and * bring differential algebra, special functions and symbolic computation communities together, to improve the facilities provided by Sage to support research in these fields. PLENARY SPEAKERS ---------------- * Peter Paule (RISC, Austria) * Alban Quadrat (INRIA Sophia Antipolis, France) * William Stein (University of Washington, USA) * Nico Temme (CWI, The Netherlands) * Felix Ulmer (IRMAR, France) The workshop will feature mathematical talks, presentations on Sage and coding sprints. It will be accessible to researchers at all levels, even those without any experience with Sage. ABOUT SAGE ---------- Sage is a free open-source mathematics software system licensed under the GPL. It combines the power of many existing open-source packages into a common Python-based interface. You will find more information about Sage on the website: http://www.sagemath.org Sage days have been wildly successful, helping to grow the developer community so that it is now the world's largest and most diverse open source mathematical software development effort. REGISTRATION ------------ There will be a registration fee of 40 Euros. Online registration will be available through the RISC Summer 2010 pages at the beginning of April 2010. You will also be able to book hotel rooms in Hagenberg during registration. Feel free to email the organizers beforehand if you intend to participate. You can also subscribe to the workshop mailing list for further announcements: http://groups.google.com/group/sagedays24 It is strongly recommended that participants bring their own laptop, as the number of on-site computers is limited. More information regarding this event is available at: http://wiki.sagemath.org/days24 We have some funding to offer support for accommodation and in limited cases travel expenses to participants from the European Community Member States (except Austria) and Associated States. A link to the application form is also available at the above website. Sincerely Yours, The organizing committee Burcin Erocal, Ralf Hemmecke and Temur Kutsia
