Sage Days 130.5 – April 27 – May 8, 2026, Montréal

A two-week SageMath Festival in Montréal

École de Technologie Supérieure (ÉTS) and Université du Québec à Montréal (UQAM), Montréal, Canada

Topics: Introduction to SageMath for Teaching and Research • Teaching with SageMath • SageMath Research and Development

Overview

As partner institutions within the Université du Québec network, UQAM and ÉTS will host a two-week Sage Days event in Montréal. This will be the 8th Sage Days held in Montréal and the first Sage Days hosted at the École de Technologie Supérieure.

The festival is structured in two complementary weeks:

• Week 1 (ÉTS) focuses on introductions to Python and SageMath for students, instructors, and researchers.

  • It is open to participants from all institutions and levels, with a particular emphasis on:

    learning Python, using SageMath for teaching, basic mathematical applications, and collaborative development tools.

• Week 2 (UQAM) takes the form of a Research Summer School.

  • It will feature a mini-course (with exercise sessions), research talks, and collaborative SageMath working sessions. The emphasis will be on geometric and algebraic combinatorics, computational experimentation, and contributing to the SageMath ecosystem.

This Sage Days is organized within the framework of an NSERC Discovery Grant entitled: “Geometric Combinatorics of Symmetric and Infinite Structures.”

Workshop Highlights

Week 1 – Introduction & Teaching (ÉTS)

• Python: syntax and basic programming concepts

• Introduction to SageMath: interfaces, syntax, and basic computations

• Applications in:
  • linear algebra
  • calculus
  • number theory
  • statistics

• Teaching mathematics with SageMath

• Git basics, workflows, and collaborative projects

Week 2 – Research & Development (UQAM)

• Mini-course with exercise sessions
• Scientific research talks
• Exchange between beginners, power users, and Sage developers

• Contributing to open-source SageMath

• Collaborative Sage development sessions

Registration

Registration is required to attend Sage Days 130.5.

• Participation is possible for either week or both weeks.

• Registration is free of charge.

• The registration form is available at https://framaforms.org/inscription-sage-days-ets-uqam-1770393973

Registration is open until March 27th.

Priority for funding support will be given to participants who register early.

Target Audience

Sage Days 130.5 is intended for:

• undergraduate and graduate students
• lecturers and professors
• researchers using computational tools

• SageMath users at all levels

• developers interested in contributing to SageMath

Beginners are welcome, especially during Week 1. Week 2 is particularly suitable for participants with some prior exposure to Python or SageMath.

Prerequisites

• Week 1: No prior knowledge of Python or SageMath is required.

• Week 2: Basic familiarity with Python and/or SageMath is recommended.

Participants are expected to bring a laptop with a working SageMath installation (or the ability to use SageMath via online platforms). If you do not have Sage installed: not a problem! Installation instructions will be provided during the event.
