If one wanted to cite an article where the listed author is a pseudonym and it is well-known that the name is a pseudonym then which name ought one use?
Normally I would just use the name listed on the paper, however there is the following situation that made me wonder: there is a paper by one Maurizio Boyarsky which is a pseudonym of one Bernard Dwork. It is somewhat 'well-known' that this is a pseudonym as it is listed in the Wikipedia article and in the MathSciNet review of the paper. However, in a certain textbook there is the line
On the other hand, Dwork in [Bo]...
and the reference at the end of the book corresponding to [Bo] is the paper of Boyarsky.
So it made me wonder, should I follow the example in the textbook or not?
EDIT: to clarify, I am not debating the entry in the bibliography, I am debating whether one should write "On the other hand, Dwork in [Bo]" or "On the other hand, Boyarsky in [Bo]".
