The "\(\displaystyle \parallel\)" symbol (as in your "\(\displaystyle \parallel\)z") is usually used to indicate parallelism, eg: \(\displaystyle AB\parallel CD\) would be read as "the line \(\displaystyle AB\) is parallel to the line \(\displaystyle CD\)" but I have never seen it used in Algebra and I have never come across the other symbol anywhere but maybe someone else will be able to enlighten us. ?View attachment 34508
This is a paper on fermat's last theorem
I located the paper here (among others), and it doesn't define the symbols. It would have been helpful to provide such contextual information.View attachment 34508

@dan. The code [ imath] \| [/imath] without the space produces [imath]\|[/imath] which can be used for parallels, norms, evenly divisible among others.As || does not appear elsewhere in the paper (and I can't even find a way to generate the /| in LaTeX) my guess is that these are typos for "divides" and "does not divide," respectively. As there are formatting typos in the paper it would not be a big surprise to find that these are as well.
For those who didn't read my links, the first defines the "parallel" symbol clearly (though I've fixed some typos):As || does not appear elsewhere in the paper (and I can't even find a way to generate the /| in LaTeX) my guess is that these are typos for "divides" and "does not divide," respectively.
