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.
Using the global search
Use the global search bar whenever you are unsure where something lives. It is designed to help you discover content, not to test your memory.
- • Example navigation path: Problems → open a problem → view its thread → submit a solution.
- • Useful keywords include Problems, Invariant Letters, Letters Studio, LaTeX Lab, Manim Lab, Events, and Chat.
- • Searching by topic also works well (e.g. ODE, Analysis, Calculus).
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
How the site fits together
Think of the platform as a loop: Programmes give direction → Problems & Courses build understanding → Resources support clarity → Events create momentum → Invariant Letters turns work into something shareable → then you return stronger.
