A Lift of the Dynkin Diagram

$A_{2l}^{(2)}$ at level $-l-\frac{1}{2}$

We consider a lift of the dynkin diagram involution of to an involution of the are of level with an anti-homogeneous realization.We classify simple highest-weight (weak) using twisted algebras and singular vectors for at boundary admissible level obtained by perše.We find that there are finitely many such modules up to isomorphism, and the (weak) that are in category for are semi-simple.We consider a lift of the dynkin diagram involution of to an involution of the are of level with an anti-homogeneous realization.We classify simple highest-weight (weak) using twisted algebras and singular vectors for at boundary admissible level obtained by perše.We find that there are finitely many such modules up to isomorphism, and the (weak) that are in category for are semi-simple.We consider a lift of the dynkin diagram involution of to an involution of the are of level with an anti-homogeneous realization.We classify simple highest-weight (weak) using twisted algebras and singular vectors for at boundary admissible level obtained by perše.We find that there are finitely many such modules up to isomorphism, and the (weak) that are in category for are semi-simple.We consider a lift of the dynkin diagram involution of to an involution of the are of level with an anti-homogeneous realization.
