## Abstract Given lists of available colors assigned to the vertices of a graph __G__, a __list coloring__ is a proper coloring of __G__ such that the color on each vertex is chosen from its list. If the lists all have size __k__, then a list coloring is __equitable__ if each color appears on at mo

Abstract
We construct graphs with lists of available colors for each vertex, such that the size of every list exceeds the maximum vertexβcolor degree, but there exists no proper coloring from the lists. This disproves a conjecture of Reed. Β© 2002 Wiley Periodicals, Inc. J Graph Theory 41: 106β109, 2002

## Abstract In 1976, Borodin conjectured that every planar graph has a 5βcoloring such that the union of every __k__ color classes with 1ββ€β__k__ββ€β4 induces a (__k__β1)βdegenerate graph. We prove the existence of such a coloring using 18 colors. Β© 2008 Wiley Periodicals, Inc. J Graph Theory 58:139
In this article we discuss the current results on the list chromatic conjecture and prove that if G is a triangle free graph with maximum degree A then xi(G) 5 9A/5. If the term "a classic" can be used about a mathematical problem less than 10 years old, then surely the following question by Jeff D
## Abstract The __square__ __G__^2^ of a graph __G__ is the graph with the same vertex set __G__ and with two vertices adjacent if their distance in __G__ is at most 2. Thomassen showed that every planar graph __G__ with maximum degree Ξ(__G__)β=β3 satisfies Ο(__G__^2^)ββ€β7. Kostochka and Woodall c
## Abstract Given a __list of boxes L__ for a graph __G__ (each vertex is assigned a finite set of colors that we call a box), we denote by __f__(__G, L__) the number of Lβ__colorings__ of __G__ (each vertex must be colored wiht a color of its box). In the case where all the boxes are identical and
