When reading publications, I find really hard to understand those math formulas/functions.

Seems like each paper uses its own notation with different symbols and syntax.

In particular some mixed calculus/set-theory where are used their own definitions which are too convoluted to remember.

When I find myself reading a calculus formula, I already forget the notations for each symbol and basically see a bunch of meaningless letters and brackets.

If someone wrote a paper, it should be possible to understand it but why is it so hard to remember the notations?

  • I'm not sure what answer are you asking for here. People introduce their own notation all the time, that's normal. Most of the time they do it because they think it is better (somehow) than the existing / alternative notation. As a referee, you can ask for notation to be changed, but if you are just reading a paper that has already been published, there's nothing you can do. – Federico Poloni Jan 2 at 16:32

    You don't say what's your study level (e.g undergraduate, master's or PhD), but your mathematical background may too weak to be able to read papers with non-negligible mathematical content. – Massimo Ortolano Jan 2 at 16:59
