Given a hypergraph H = (V,E), a coloring of its vertices is said to be
conflict-free if for every hyperedge S ∈ E there is at least one
vertex whose color is distinct from the colors of all other vertices
in S. The study of this notion is motivated by frequency assignment
problems in wireless networks. We introduce and study the
list-coloring (or choice) version of this notion. Joint work with
Panagiotis Cheilaris.
