Choosability of Graphs with Bounded Order: Ohba's Conjecture and Beyond

Jonathan A. Noel

The \emph{choice number} of a graph $G$ , denoted $ch (G)$ , is the minimum integer $k$ such that for any assignment of lists of size $k$ to the vertices of $G$ , there is a proper co…

Beyond Ohba's Conjecture: A bound on the choice number of $k$ -chromatic graphs with $n$ vertices

Jonathan A. Noel, Douglas B. West, Hehui Wu +1

Let $ch (G)$ denote the choice number of a graph $G$ (also called "list chromatic number" or "choosability" of $G$ ). Noel, Reed, and Wu proved the conjecture of Ohba that $\t…
