Retractions in mathematical journals The number of retractions in some scientific fields like medicine, life and material related science seems rising in the past years. However, retractions in mathematics seem rare because of its rigorous nature. I wonder if there are retractions in mathematical journals.
The Daniel Biss case is one example where the retraction is due to legitimate mistakes (not misconduct). These retractions are rare because much of the time, incorrect proofs can still be salvaged with some work (recall Wiles and Taylor) and even papers with wrong results often contain enough correct material to be considered useful. Also, there are much fewer people that have the time to properly evaluate a paper in mathematics than in (say) psychology, where anyone with a decent understanding of statistical fallacies can find half a dozen bad studies per day.

There are also, quite likely, some cases where plagiarism has led to retractions.

Then there is the Ted Hill GMVH controversy (Quillette, Gowers's blog 1, Gowers's blog 2, Retraction Watch). NYJM has removed that paper from its archives, which can be construed as a kind of informal retraction, albeit easier to construe as a mess-up in the face of unexpected hostility from parts of the community. (The explanation given for the retraction is that the paper did not fit the journal's scope and level; note, however, that this is an extremely unusual grounds for retraction in academic publishing.)

RetractionWatch has a tag for retractions in mathematics.
