Extended affine Lie algebras and descent theory

• Author / Creator

  Guo, Hongyan

• This thesis gives two realizations of fgc extended affine Lie algebras, as fixed point subalgebras and as descended objects. Fgc stands for “finitely generated over the centroid ” . All extended affine Lie algebras are fgc except for a well understood family of type A. In the process, the Lie algebra of derivations of certain Lie algebras (including multiloop algebras) are also studied from the twisted forms point of view.
