Bounds For Partial List Colourings
نویسندگان
چکیده
Let G be a simple graph on n vertices with list chromatic number χl = s. If each vertex of G is assigned a list of t colours Albertson, Grossman and Haas [1] asked how many of the vertices, λ t,s, are necessarily colourable from these lists? They conjectured that λt,s ≥ tn/s. Their work was extended by Chappell [2]. We improve the known lower bounds for λt,s. Primary AMS subject classification: 05C15

Generalized Colourings (Matrix Partitions) of Cographs
Ordinary colourings of cographs are well understood; we focus on more general colourings, known as matrix partitions. We show that all matrix partition problems for cographs admit polynomial time algorithms and forbidden induced subgraph characterizations, even for the list version of the problems. Cographs are the largest natural class of graphs that have been shown to have this property. We b...
متن کاملOn generalized list colourings of graphs
Vizing [15] and Erdös et al. [8] independently introduce the idea of considering list-colouring and k-choosability. In the both papers the choosability version of Brooks’ theorem [4] was proved but the choosability version of Gallai’s theorem [9] was proved independently by Thomassen [14] and by Kostochka et al. [11]. In [3] some extensions of these two basic theorems to (P, k)-choosability hav...
متن کاملBounds on the achromatic number of partial triple systems
A complete k-colouring of a hypergraph is an assignment of k colours to the points such that (1) there is no monochromatic hyperedge, and (2) identifying any two colours produces a monochromatic hyperedge. The achromatic number of a hypergraph is the maximum k such that it admits a complete k-colouring. We determine the maximum possible achromatic number among all maximal partial triple systems...
متن کاملBalanced list edge-colourings of bipartite graphs
Galvin solved the Dinitz conjecture by proving that bipartite graphs are ∆edge-choosable. We improve Galvin’s method and deduce from any colouring of the edges of bipartite graph G some further list edge-colouring properties of G. In particular, for bipartite graphs, it follows from the existence of balanced bipartite edge-colourings that balanced list edge-colourings exist as well. While the k...
متن کاملAlgorithmic Aspects Of Partial List Colourings
Received Let G = (V; E) be a graph with n vertices, chromatic number (G) and list chromatic number`(G): Suppose each vertex of V (G) is assigned a list of t colors. Albertson, Grossman and Haas 1] conjectured that at least t ` (G) n vertices can be colored properly from these lists. Albertson et. al. 1] and Chappell 3] proved partial results concerning this conjecture. This paper presents algor...
