I asked a question, and I received an answer (see here: Non-isomorphicity of certain fields.). But the answer is not clear to me, and it has too many ambiguities for me. I've tried too much and thought a lot about it, but I cannot understand it. I think this phenomenon has happened before to me. What suggestions do you recommend me to do?
Edited: I'm embarrassed to say this, I do not think that is a mathematical proof, and I think it has a fundamental bug that cannot be fixed. Of course, I can not tell if it is wrong or not. (I do not want to discuss more on this question, I just add more details about my opinion on that question, to be more precise.)
