= Sage Days 28: Dynamics, geometry, combinatorics... = This workshop will offer a gentle introduction to the open source mathematical software [[https://www.sagemath.org|Sage]], with an emphasis on dynamics and geometry. Talks will be in French or English depending on the participants. == Dates: 17 to 19 January 2011 == Some people will stay for the whole week (Jan 17 - 21) to develop. == Location == Laboratoire de Mathématiques d'Orsay (Université Paris-Sud 11), Orsay, France. All talks and tutorials will be held in building 430. The main lecture room will be salle Lederer (ground floor). There will be another room available for parallel sessions. Tea/coffee will be served in the tea room in the first floor of the same building.
