Quote From DrJeckyll:
Hi Chococake,
I always put both my supervisors regardless their contribution. I am in the sciences and I put my first supervisor as the last author, which is a way to show who is the boss:)
Generally, I receive a lot of support from them, and I feel that putting their names is the least I can do to acknowledge it.
Yep, agree with the above- and it's exactly what I do. I've published 3 papers, and both sups on the paper regardless of contribution.
My first sup who is a prof goes last, the other who is a phd oes second, and she almost always contributes more than the prof.
