About SageMath

Sage is a mature, comprehensive, free (open-source) mathematics software system based on Python, licensed under the GNU General Public License, that integrates computer algebra facilities and general computational packages.

Sage, first released in 2005, in over a decade of incubation in the SageMath distribution, comprising 293 software packages, has grown its own library of 1000 Cython and over 4400 Python modules, ranging from sage.algebras.* over sage.geometry.* to sage.tensor.*], with a total of over 2.2 million lines of code. [[https://wiki.sagemath.org/ReleaseTours/sage-9.0, released in January 2020, completed the transition of the Sage library to Python 3.

Presentations: What's New in Sage 9.1

Organizer: Matthias Köppe

Following https://wiki.sagemath.org/ReleaseTours/sage-9.1

SageMath, Mathematical Libraries, and the Landscape of Computer Algebra Software

TBA

Big-picture Development Discussions

• Modularization of Sage
• Integration with the Python community
• The next 10 years of Sage development

Nettoyage de Printemps (Spring Cleaning)

Organizers: Sébastien Labbé, Vincent Delecroix, Xavier Caruso

The aim is to go through the already existing trac tickets and

• confirm if the bug is still present on recent development versions
• provide code
• make reviews

Useful links

• trac tickets sorted by time (oldest first)

• trac tickets reported as "defect" (as opposed to enhancement) (oldest first)
