https://math.stackexchange.com/q/4599061/1020656 I asked this question some days ago and also got some clear answers.( though I didn't marked any answer at that time as accepted because on that day I could not understand). However I found that this question was deleted because it don't "meet community guidelines" and asks me to "show additional efforts, definitions" ,etc.
1-If you were at my situation and were to ask this question, what additional things would you have given?
2-If the question is well-written to be clear and also shows my effort (which I think it does) , then I want to ask that- Is it necessary for every question to expand anyhow the self's work to make it look bigger and prove the efforts and works, if instead it can be done in a simple or short way
Thanks very much.
