On chain polynomials of posets

2024-06-26

Speaker: Leonardo Saud Maia Leite (KTH Royal Institute of Technology, Sweden)

The chain polynomial of a finite lattice \( \mathcal{L} \) is given by \( p_\mathcal{L} (x) = \sum_{k \geq 0} c_k(\mathcal{L})x^k \), where \( c_k(\mathcal{L}) \) is the number of chains of length \( k \) in \( \mathcal{L} \). The chain polynomials of posets in several important classes have...
