Abstract

We consider the principal subspaces of certain level k1k\geqslant 1 integrable highest weight modules and generalized Verma modules for the untwisted affine Lie algebras in types DD, EE and FF. Generalizing the approach of G. Georgiev we construct their quasi-particle bases. We use the bases to derive presentations of the principal subspaces, calculate their character formulae and find some new combinatorial identities.
