'''''April 17-21, 2017, Montreal, Canada'''''

~-(originally planned May 8-12, 2017)-~

At the occasion of the thematic semester [[http://www.crm.umontreal.ca/Combinatorics2017/index.php/|Algebra and words in combinatorics]] from March to July 2017, a [[https://wiki.sagemath.org/Workshops|Sage Days]] will be held at [[http://lacim.uqam.ca/en/|Laboratoire de combinatoire et d'informatique mathématique (LaCIM)]] of [[http://www.uqam.ca/|Université du Québec à Montréal]].

'''As Monday April 17th is a holiday, the official program starts on
Tuesday 18th. Nevertheless, everyone is encouraged to join on Monday
for informal coding sprints and tutorials.'''

== Where ==

Room PK-4323 of the [[http://carte.uqam.ca/pavillon-pk|Président-Kennedy building]], 201, av. du Président-Kennedy, Montréal.

== Target audience ==

 * Newcomers to advanced users that want to learn more about and get training on the open source mathematical system [[http://sagemath.org|SageMath]] and related software.
 * (would be) developers that want to participate to coding sprints.

== Invited speakers ==

 * [[http://bergeron.math.uqam.ca/|François Bergeron]] (LaCIM, Université du Québec à Montréal); topic: experimental mathematics
 * [[http://www-groups.mcs.st-andrews.ac.uk/~jamesm|James Mitchell]] (CIRCA, University of St Andrews); topic: [[https://gap-packages.github.io/Semigroups/|GAP's semigroup package]] and the [[https://james-d-mitchell.github.io/libsemigroups/|libsemigroup]] C++ library [[https://goo.gl/NvRrAv|slides]]
 * ThierryMonteil (CNRS, LIPN, Université Paris Nord); topics: "representations of real and complex numbers in Sage" and "gems of [[https://ask.sagemath.org|ask.sagemath.org]]"
 * [[http://math.bu.edu/people/jbala/|Jennifer  Balakrishnan]] (Boston University); topic: Three problems in number theory

== Organizers ==

 * Sébastien Labbé (CNRS, LaBRI, Université de Bordeaux)
 * Nicolas M. Thiéry (Université Paris Sud)

== Themes ==

The themes of the projects and tutorials will be picked by the
participants, and are likely to relate to the four main workshops held
during the semester:

 * Combinatorics on Words and Tilings (March 27 -- April 7 2017)
 * Bridges between Automatic Sequences, Algebra and Number Theory (April 24 -- May 5 2017) 
 * Algebraic and Geometric Combinatorics of Reflection Groups (May 29 -- June 9 2017)
 * Equivariant Combinatorics (June 12-23 2017)

== Projects ==

== Working on tutorials in autonomy ==

We suggest to use the following source of tutorials:

 * Sage documentation (especially thematic tutorials) : http://doc.sagemath.org/
   * if you want to work on some tutorials from a jupyter notebooks, they are automatically (dirty) exported at https://days86.metelu.net/sage/sage_official_material
 * Sébastien's lecture : http://www.slabbe.org/Enseignements/MATH2010/notesdecours/
 * Sébastien's 150 exercises : http://www.slabbe.org/Enseignements/MATH2010/exercices.pdf
 * Thierry's worksheets (updated along the week) : https://days86.metelu.net/
 * Exercises to be done for the April 24-28 School at CRM : [[attachment:exercices_school_april24.pdf]]

== Schedule ==

Empty slots are made of Tutorials in autonomy and coding sprints.
