Since I self-study mathematical analysis without formal teacher, I can only appeal to help from out site most of the time. It's obvious that to grasp the underlying concepts in mathematics, we must roll the sleeves and solve problems.
It's clear that there are actually mistakes and misunderstanding that are too subtle for me to recognize, so it's very natural for me to ask for proof verifications.
Even though I tried to write my proofs as detailed and clear as possible, they seem to attract little attention from other users. It seems to me that proof checking is a boring and tedious job, but it is essential for me (and possibly for all of us) to know whether and where I get wrong.
How can I make my post for proof verification more attractive and consequently attract more attention?
Below are questions that i have not received any answer. Most of them are related to Cantor-Bernstein-Schröder theorem. It would be great if someone can help me improve them so that they get an answer. Thank you so much!
