Citing article where listed author is pseudonym 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]".
Always use the name that is used on the article/book you are referring to. 

If someone searches for an article referred to as being written by Dwork, but the name on the article is Boyarsky it will only cause confusion about whether this is the article they are looking for.

Regarding the pseudonym: I would not mention it at all. It is up to the author when or where they reveal that they use a pseudonym. Even when it is commonly known I would still not do this, except when you have explicit permission from the user of the pseudonym. This way you avoid spreading awareness of the use of the pseudonym in a situation where the user may not desire this. One exception could be when there is suspicion of the pseudonym being used with ill intent. Generally though I think it is good to be cautious about such revelations.
