Licence

The mathematical content of this library — the definitions, statements, proofs, examples, counterexamples and page summaries — is licensed under Creative Commons Attribution-ShareAlike 4.0 International (CC BY-SA 4.0).

What you may do

Share it in any medium or format, and adapt it — remix, transform and build upon it — for any purpose, including commercially. Those permissions cannot be revoked while you follow the terms below.

On two conditions

Attribution. Give credit, link to the licence, and say whether you made changes. A line like this is enough:

"Alphabeta Math" by Prestige Intelligence, https://alphabetamath.cc/, licensed under CC BY-SA 4.0.

ShareAlike. If you remix or build upon this material, you must distribute your contribution under the same licence. This is the condition that keeps derived work as freely available as the original.

What is not covered

The application that renders this library is not covered by this licence, and neither is the Prestige Intelligence name or mark. Cited sources remain under whatever terms their own authors set — each item lists its sources, and where the library restates a result from the literature it says so in that item’s provenance labels.

Some items are recorded with a citation but not proved here. Those statements are not this library’s work; the citation names where they come from. See about this library for how that is marked.
