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]".
If the pseudonym is not listed in that book and the author refers to [Bo] as "Dwork" that would cause a lot of confusion, in my opinion. Personally, I'd go with a consistent naming of the author, be it pseudonym or real name. The choice which name you choose depends on which name is better known or listed on the source. So it should be either
On the other hand, Dwork in [Dw] ...
On the other hand, Boyarsky in [Bo] ...
to avoid any confusion.
