When one goes from one grant to another, there are a few papers that are in the pipeline during the process. I have one such paper that was in submission when I switched grants. Submitted on the first grant, and then revised and resubmitted on the second and with additional changes on the second. This paper was then accepted. I acknowledged both grants in the final transcript as work was done to the paper on both grants.
The second grant agency asks for updates of research outcomes and consequences during the grant in a very black and white way of listing publications that are a product of the research. Is this paper considered a research outcome to the second grant?
This is in mathematics, if that helps, and there was some math to be done to fix the referee's complaint(s).
