How to use this site

A short orientation for students, contributors, and visitors: where to start, how the sections connect, and how to use the current platform meaningfully.

Start in 60 seconds

  • Open Programmes: choose one academic or skill track to follow.
  • Visit Problems: read one problem carefully and explore its discussion thread (solutions submitted there are written in LaTeX).
  • Use Resources: access labs and templates that support your learning and writing.
  • Open Invariant Letters: read polished write-ups and announcements, or use Letters Studio when you are ready to publish.

Choose your path

  • Students: Programmes → Problems → Resources → Courses
  • Visitors: Programmes → Events → Invariant Letters
  • Career-focused: Careers → Resources → Problems → Invariant Letters
  • Writers / contributors: Invariant Letters → Resources → Contact
