If the Problems Hub helped you learn, or an online event helped you stay connected, your support keeps this platform stable and growing.
InvariantMath is built for long-term learning: problem threads, searchable archives, online events, and a growing set of resources — designed to be calm, organised, and easy to return to.
Support here helps keep the platform reliable, improve the learning experience, and ensure long-term sustainability.
- • Help with platform costs: hosting, domain, storage, email, and the small expenses that keep pages fast and reliable.
- • Sponsor a specific upgrade: search improvements, better archiving, mobile stability, or a new set of learning tools.
- • Support the learning: books, software access, mentoring, or resources that help students study and research more seriously.
- • Support events: help make online talks possible, or help keep recordings accessible and well-archived.
- • Share it with the right people: invite someone to post a solution, share an event link, or recommend the Problems area to a student who would benefit from it.
