comment How to prove a certain theorem about algebraic function fields
You should make your question self-contained, so that people can understand it without looking at the book.

Indeed, that looks like a nice article with beautiful pictures. Now I just need to find a couple of hours to learn Farsi ...

comment Coboundary of a cup-product
I don't think that this makes sense. Note that $\partial_p\alpha$ lies in $H^*(X,A)$ and $\beta$ lies in $H^*(A)$, and there is no natural product $H^*(X,A)\otimes H^*(A)\to H^*(X,A)$ so $\partial_p\alpha\cup\beta$ is not defined.

comment Formal group law over $\mathbb{F}_p$
Bakuradze has just put a proof on the arxiv at arxiv.org/pdf/1502.04152v1.pdf. This may just be a coincidence; he does not refer to the discussion here, I don't know if he has seen it.
