- Abstract: In this talk, we discuss various recent approaches to obtaining the characters of principal subspaces of irreducible highest weight integrable representations of certain twisted affine Lie algebras. In particular, we review past results using presentations and exact sequences, a technique which has proven to be powerful at level k=1, and discuss new results using combinatorial bases for these structures for levels k>1.
