WebJul 7, 2015 · Cartan subalgebras of a complex Lie algebra g are known to be unique up to automorphisms of g; for example, choosing a Cartan subalgebra of g l n ( C) is more or less equivalent to choosing a basis of C n (the Cartan subalgebra consists of matrices which are diagonal when written in that basis). Share Cite Follow answered Jul 7, 2015 at 17:57 Webstring theory demystified was a fun easy read and seemed to cover a decent amount of the same material as Zwiebach. It only covers how to do calculations in the absolute simplest cases. You will see actual calculations involving lagrangians and the prediction of the graviton, etc. It gives a taste.
