I am PhD student in mathematics and am writing a joint paper with a computer science PhD student. As we will submit the paper to a computer science journal we discussed the author ordering and agreed to equal distributions for us PhD students and our respective supervisors.
The computer science student has now ordered the author names in an non-alphabetical order for us PhD students, which makes him the first author, and an alphabetical order for the supervisors, which makes his professor the last author.
Is this common practice in computer sciences? I can understand that it is their community, but this confuses me. I think it should be at least in the same order for both categories.
My supervisor told me to talk to the other PhD student. How can I address this issue without offending anyone?
How does equal distribution authorship in computer science work, anyway?
Edit: I just don't want to be fooled. I understand that being first author is important in computer science, this is why we decided to have both PhD students as co-first authors. Our supervisors are co-last authors. Having a non-alphabetical order for the PhD students and an alphabetical order for the supervisors seems to abolish this equal distributions again to me. I just have no idea how this equal distribution thing works and how to address this issue without messing up everything. I am not sure if we PhD students will work together again, but I could imagine that our supervisors do.
