Should I take consent before listing referee names? I am about to submit my research article in a Mathematics journal and the online system is asking to mention three Referee/Reviewer names.
Should I take the consent of a few experts in my topic before I enlist three expert names as referees, by individually mailing them?
I think, I should take.
Any suggestions and advice regarding the question, please?
No. You do not need consent from them. There is no convention to do that.
Usually, the whole peer review process is an anonymous one, with the selection of reviewers occuring at the editors' full discretion. The editors have various channels to find suitable reviewers, and they usually do not tell the reviewers (nor the authors) how they came across them.
