Statements of authors' contributions appear to be a standard practice in journal papers from experimental sciences or similar fields. Yet I haven't seen many such examples in mathematics.
I'm wondering if it will be appropriate to have a statement of contributions in a paper (algebraic geometry + some applications) that states the contribution of a coauthor who is my undergraduate student. If yes, will it be strange if the statement only explain the contribution of this student coauthor but not other coauthors?
The intended purpose for such a statement is twofold:
- To highlight the real (and nontrivial) contribution of an undergraduate student which may potentially be helpful for this student's career.
- To avoid opposition from coauthors who may question listing a student as an author. (EDIT: To avoid opposition from coauthors who may question the actual amount of contribution)
EDIT: One crucial detail was left as it was somewhat subjective. The student's contribution is small but nontrivial in my opinion. It is only a nice-to-have result. This paper can live without it. But I believe it adds some depth to this paper. So the necessity of this student's contribution is debatable. I'd hope to preemptively eliminate this debate --- why argue with someone you'll work with for a long time.
