I'm making the final edits for a paper and I have a question more about the etiquette. I want to use a theorem from another paper and its obvious I have to cite it, but do I need to prove it too? I previously just used it as a fact and cited it, but it was recommended to make it into a theorem in order to make it easier to reference later.
If I do need to prove it, can I just use the proof from the reference (with citation, of course)?
The paper is on graph theory, specifically exponential domination. Thanks!
No you can state and refer to original paper as reference.
