Guys. This is my problem with reading white papers. People use notations and assumptions which I am not familiar with. Hence, I have to go decipher what people are trying to day. There needs to be a course for math notation. Is there a book or a online course I can take to familiarize myself with math as a language.
They use (slighly) different notions in different parts of mathematics. And usually, it's not just the notation that's difficult, but the concepts themselves.
In general, you are best off studying introductory texts to the topics you are interested. You will pick up the notation.
