About Maddy
A public record of learning mathematics.
The notes keep the work that usually disappears: the example that fixed an intuition, the hypothesis a first proof missed, and the question left unresolved.
What belongs here
Each article handles one mathematical question. Concept notes connect a definition to examples. Proof notes expose the step carrying the argument. Problems focus on strategy and failed approaches. Notebook entries hold work that has not settled yet.
How the archive is organized
Analysis, algebra, geometry, probability, and combinatorics provide broad coordinates. Series and prerequisites record the useful connections between individual articles.
Corrections
The source, article history, and deployment process are public in the Maddy repository. Open an issue when a statement lacks a hypothesis or a proof can be made cleaner.
