✦ Synopsis


Let Ο‡ l (G), Ο‡ l (G), Ο‡ l (G), and (G) denote, respectively, the list chromatic number, the list chromatic index, the list total chromatic number, and the maximum degree of a non-trivial connected outerplane graph G. We prove the following results. ( 1

and only if G is an odd cycle. This proves the well-known list edge coloring conjecture for outerplane graphs.

This proves a conjecture of O. V. Borodin, A. V. Kostochka and D. R. Woodall, List edge and list total coloring of multigraphs,

A graph G = (V , E) is called (k, k )-total weight choosable if the following holds: For any total list assignment L which assigns to each vertex x a set L(x) of k real numbers, and assigns to each edge e a set L(e) of k real numbers, there is a mapping f : V βˆͺE β†’ R such that f (y) ∈ L(y) for any y

## Abstract Suppose the edges of a graph __G__ are assigned 3‐element lists of real weights. Is it possible to choose a weight for each edge from its list so that the sums of weights around adjacent vertices were different? We prove that the answer is positive for several classes of graphs, includi

This paper discusses the circular version of list coloring of graphs. We give two definitions of the circular list chromatic number (or circular choosability) c;l Γ°GÞ of a graph G and prove that they are equivalent. Then we prove that for any graph G, c;l Γ°GÞ ! l Γ°GÞ Γ€ 1. Examples are given to show

## Abstract A plane graph __G__ is coupled __k__‐choosable if, for any list assignment __L__ satisfying $|{{L}}({{x}})|= {{k}}$ for every ${{x}}\in {{V}}({{G}})\cup {{F}}({{G}})$, there is a coloring that assigns to each vertex and each face a color from its list such that any two adjacent or incid
