I am looking for a road to understanding what quasi-algebraically closed fields are with the ultimate goal of understanding the paper by Lang 1952.
My current background is the first 6 chapters from Milne's notes here. Currently I am also studying the 7th chapter from the same notes and the chapter on Brauer groups from Milne's notes on class field theory.
I am also familiar with Russian besides English. Apologizes if the question is not placed in an appropriate place, but I really seek some help here.
EDIT: At the advice given in a comment here, I deleted the post from here and moved the question to Stack Exchange, but it did not receive any answers there, so I undeleted this post.
