:Category:Pseudonymous mathematicians
This category collects authors of mathematical research or research-level exposition, who have been identified as pseudonyms for one or more mathematicians: Most notably, Nicolas Bourbaki.
It also includes pseudonymous mathematical humor, such as parodies of mathematical papers, written by research mathematicians for their peers and published in professional venues: For example, the lion-hunting papers of H. Pétard (Ralph Boas Jr.).
