Bases of Feigin-Stoyanovsky's type subspaces for $C_{\ell }^{(1)}$

Ivana Baranović, Mirko Primc, Goran Trupčević

In this paper we construct combinatorial bases of Feigin-Stoyanovsky's type subspaces of standard modules for level $k$ affine Lie algebra $C_{\ell }^{(1)}$. We prove spanning by usin…
