A follow-up question to this: Citing a math theorem with errors
Let's say a paper A has some error in a proof of a theorem and then I publish a paper B citing the theorem and its proof and also indicate the error in the proof and provide a corrected proof.
And now say I want to use this theorem in paper A for another paper C, what do I do? (Let's say the paper wasn't corrected.)
- Copy all the stuff I said in my previous paper B to my new paper C, as if paper B never existed. (assume paper B is otherwise irrelevant to paper C.)
- Cite both papers A and B.
- Cite only B, since it also has a citation of A.
