Pre-event Program

The pre-event consists of an online series of preparatory lectures preceding the main CIMPA School. It offers a first introduction to some of the key topics of the school and helps participants build the background needed to follow the lectures more comfortably.

Date and Time

Platform

The pre-event is conducted online via Teams (or BigBlueButton). Participants receive the connection link by email prior to each lecture.

Goals of the Pre-event Lectures

Goals

  • Give a first overview of the school and its topics (combinatorics and graph theory).
  • Reactivate prior knowledge when relevant.
  • Introduce basic tools and ideas to reduce the initial gap.
  • Stay informal to encourage questions and discussion.

What this is not

  • A full or self-contained course.
  • A rigorous or exhaustive reference.
  • A fixed standard for notation or definitions.
    • Expect differences with your actual lecturers.
    • Use this as intuition-building support, not as the final framework.

Important

  • This is a fast-paced introduction, not a complete learning path.
  • You are expected to complete and consolidate the material during the course.
