摘要：

By using the known description of combinatorial bases for Feigin-Stoyanovsky's type subspaces of standard modules for affine Lie algebra sl(l + 1, C), as well as certain intertwining operators between standard modules, we obtain exact sequences of Feigin-Stoyanovsky's type subspaces at fixed level k. This directly leads to systems of recurrence relations for formal characters of those subspaces. (C) 2008 Elsevier B.V. All rights reserved.
