I desperately need to read the paper  before meeting a would-be supervisor, but with limited undergraduate knowledge that I have like Aluffi's Algebra and Churchill's Complex Analysis, not even one sentence of the paper is readable to me, so I even don't know what area of mathematics is it about!
What is the necessary prerequisite knowledge to be able to understand the mentioned paper and the best introductory books written about? Thank you!
