Abstract:
We establish the conjugacy of Cartan subalgebras for extended affine Lie
algebras whose centreless core is “of type A”, i. e., $\ell \times
\ell$-matrices over a quantum torus $\mathcal{Q}$ whose trace lies
in the commutator space of $\mathcal{Q}$. This settles the last outstanding
part of the conjugacy problem for Extended Affine Lie Algebras that remained
open.
Key words and phrases:
extended affine Lie algebras, Lie torus, Cartan subalgebras, quantum
torus, special linear Lie algebra.
