Errata and marginalia

This is an archive of my comments and corrections on other authors' mathematical works. This includes lists of errata, alternative proofs, omitted details and the occasional (simple) generalization.

Caveat lector: Do not take my lists of errata at face value. There is no guarantee that what I claim to be errors are actually errors, nor that what I believe to be corrections is more correct than the originals. If you have comments on my comments, please let me know at, where A = darijgrinberg and B = gmail.

If you are looking for my errata for elementary geometry books, they are elsewhere.
