I am currently a graduate student in mathematics with an interest in vertex algebras. I am comfortable with the algebraic aspects and would like to learn more about the geometric aspects. The issue is that I'm finding the standard text on the subject (Vertex Algebras and Algebraic Curves by Frenkel and Ben-Zvi) to be very challenging and almost inaccessible. Apart from this text, does anyone have any recommendations for texts to learn about geometric aspects of the following: vertex algebras, conformal blocks, the KZ equations? I'm struggling to find any alternative texts on these topics, let alone more accessible ones.
