here is the case. I must write an essay about Borel sets (Introduction to Measure Theory course). Taking in account I've never written any mathematical essays before, I consider this as my first research work.
So, I am a little bit confused about the structure of this work. How do you think, which are those things I must obligatory include about this topic, some essential points?
Also, I am thinking of using math article databases, can you advise any?
