Result and theorem are two different things. I don't think you can compare them. You compare results with results, not results with theorem. Or do you mean 'results expected from theorem A'?In paper , we obtained an original result which is more general than Theorem A.
Why 'original result'? How many results are there?
not a teacherHowever, since paper  was unpublished has not been published, we must giveshow the detailed proof of Theorem A here.
