The textbook of which I am interested in obtaining some input are the following: Cohn- Measure Theory Wheeden and Zygmund - Measure and Integral Folland- Real Analysis. Let me be frank here, I am looking for the easiest textbook. I will be working through the text for a self-study project. As I mentioned in a previous thread, I will be using the text alongside Kreyszig's Functional Analysis (which is already proving to be exceptionally clear). Thank you very much in advance for your input. Other book suggestions are very welcomed.
