چکیده
We extend a characterization of degree-choosable graphs due to Borodin [1], and Erdős, Rubin and Taylor [2], to circular list-colorings.

Circular choosability of graphs
This paper discusses the circular version of list coloring of graphs. We give two definitions of the circular list chromatic number (or circular choosability) of a graph and prove that they are equivalent. Then we prove that for any graph , . Examples are given to show that this bound is sharp in the sense that for any , there is a graph with . It is also proved that -degenerate graphs have . T...
متن کاملBounds on circular consecutive choosability
The circular consecutive choosability chcc(G) of a graph G has been recently introduced in [2]. In this paper we prove upper bounds on chcc for series-parallel graphs, planar graphs and k-choosable graphs. Our bounds are tight for classes of series-parallel graphs and k-choosable graphs for k ≥ 3. Then we study the circular consecutive choosability of generalized theta graphs. Lower bounds for ...
متن کاملCircular choosability is rational
The circular choosability or circular list chromatic number of a graph is a list-version of the circular chromatic number, introduced by Mohar [4] and studied in [17, 2, 5, 7, 8, 15] and [10]. One of the nice properties that the circular chromatic number enjoys is that it is a rational number for all finite graphs G (see for instance [16]), and a fundamental question, posed by Zhu [17] and reit...
متن کاملOn two questions about circular choosability
We answer two questions of Zhu on circular choosability of graphs. We show that the circular list chromatic number of an even cycle is equal to 2 and give an example of a graph for which the infimum in the definition of the circular list chromatic number is not attained.
متن کاملk-forested choosability of graphs with bounded maximum average degree
A proper vertex coloring of a simple graph is $k$-forested if the graph induced by the vertices of any two color classes is a forest with maximum degree less than $k$. A graph is $k$-forested $q$-choosable if for a given list of $q$ colors associated with each vertex $v$, there exists a $k$-forested coloring of $G$ such that each vertex receives a color from its own list. In this paper, we prov...
