Comparing list-color functions of uniform hypergraphs with their chromatic polynomials

Fengming Dong, Meiqiao Zhang

In [J. Combin. Theory Ser. B 161 (2023), 109--119], the authors showed that the list-color function $P_{l} (G, k)$ of any simple graph $G$ of size $m$ coincides with its chromatic poly…

Comparing list-color functions of uniform hypergraphs with their chromatic polynomials (III)

Fengming Dong, Meiqiao Zhang

For a hypergraph $H$ , let $P (H, k)$ and $P_{l} (H, k)$ be its chromatic polynomial and list-color function respectively, and let $I ¨ ^{'} (H)$ be the least non-ne…
