> If you don’t know the notation, you almost surely don’t know the concepts themselves, I find that this isn't true. I spent quite a few years working on number theory problems on my own, just out of interest. I developed several techniques that I just couldn't understand when other people used them, because they had really weird notations, like |x-Σbⁿdₙ|<ϵ, with no definitions for any of the letters. (Feel free to guess what that means. Hint: nothing to do with set membership.) Sure, you can work it out if you can compare several different papers, so it's only a barrier for a few days… but it's still a barrier.
