A paper contains three theorems. After submitting the paper, the author finds out that one of their theorems was already published by someone else with stronger result. Although their result is not as strong, the author’s method is much simpler.
They have two choices:
- Keep the theorem and mention the result already done, and state that the method in current paper is simpler.
- Just drop the theorem from the paper, and keep 2 theorems instead.
Given that they have already submitted the paper, the author just has to wait for referee's report. So their choice will come after the decision of the referee.
What would be the best choice?
