Parafermionic bases of standard modules for twisted affine Lie algebras of type $A_{2l-1}^{(2)}$, $D_{l+1}^{(2)}$, $E_6^{(2)}$ and $D_4^{(3)}$

Abstract: Using the bases of principal subspaces for twisted affine Lie algebras except A(2) 2l by Butorac and Sadowski, we construct bases of the highest weight modules of highest weight kΛ 0 and parafermionic spases for the same affine Lie algebras. As a result, we obtain their character formulas conjectured in [14].
