Abstract or Additional Information

Weyl modules are universal objects that arise in the study of the category of finite dimensional representations of loop Lie algebras. I will explain their construction for twisted affine Lie algebras and sketch the proof of the main structural result relating global and local Weyl modules with an emphasis on the particularly delicate case of affine Lie algebras of type $A_{2n}^{(2)}$.
