Combinatorial bases of principal subspaces for affine Lie algebra of type B_2^(1)

Marijana Butorac

We consider principal subspaces $W_{L(k{\Lambda }_0)}$ and $W_{N(k{\Lambda }_0)}$ of standard module $L(k{\Lambda }_0)$ and generalized Verma module $N(k{\Lambda }_0)$ at level $k\ge 1$ for affine Lie algebra of typ…
