String theory cartan generators
WebMay 5, 2015 · 1 Answer Sorted by: 1 The thing is, by multiplying the weights in den Dynkin basis with the metric tensor, we get the weights in the simple root basis. If we want to know the weights in terms of the Cartan generator H 1, H 2,... eigenvalues, we need to use the simple roots in this basis. http://www-f1.ijs.si/~ziherl/Greljo12.pdf
