I have a need to modify Erdős' proof of the Sylvester-Schur Theorem to prove something stronger. See my working document at http://math.rudytoody.us/ or http://math.rudytoody.us/OppermannTheorem.pdf

If I have to modify most of the proof, I will use the entire proof (with proper attribution, of course.) However, I don't believe I will need to do that. So, how much should I show of the original? Could I do a line-by-line comparison of the changes? If I only change a few variables, could I do something along the lines of, "By changing variables a, b, c and relaxing condition x, it's easy to see that Erdős' proof arrives at the same conclusion without breaking the original."

Some suggestions would be appreciated. Thanks.

this audienceto not have the Erdös paper handy, so probably your including a complete proof would be best. $\endgroup$this audience, you should provide a complete statement and proof. You can then comment on how the proof compares to that of Erdös if you like, or say that it is patterned after that of Erdös, or whatever. BTW: I didn't feel like copying and entering your link into my browser -- laziness. Why don't you provide a direct link? $\endgroup$9more comments
