I read an article published in a High Impact Factor journal and on reading I find that almost all of the proofs could have been done in an easy way.
I devised easy techniques myself and I find that the results obtained in that paper match mine.
Shall I publish my easy techniques stating in my paper that I have found easy proof techniques for the paper already published? Is it publishable?
How shall I address the Editor and let him/her know that I have obtained the same results but using much easier techniques?
How should I give a title for my manuscript?
