No, my goal is not to understand string theory. In fact, I didn't know that you could apply it to string theory. For my master program in mathematics I must explain how the proof of Bergers Theorem using Extrinsic Holonomy theory was done in the article written by Carlos Olmos.
I still...
I am trying to learn about Holonomy groups. My objective is to read Submanifolds and Holonomy from Berndt, Olmos and Console. I know I need a lot of prerequisites before understanding that book. So I started first reading Lee's book of Smooth Manifolds (I readed it until the Submanifolds...
