I want to learn graph minor theory. Now i have read the very basic things and the overview from the book of R.Diestel but proceeding further is getting difficult. Currently, I am also following the video lectures by Jim Geelan on graph minor theory.
Please suggest more books/monographs/lecture notes on graph minor theory. In case there is none, please suggest a systematic way to learn the concepts.
I posted the same question here, but not sure if it reached the right community.
