On the oriented coloring of the disjoint union of graphs
LetG⃗ = (V, A) be an oriented graph andGthe underlying graph ofG⃗. Anorientedk-coloringofG⃗ is a partition ofVintokcolor classes, such that there is no pair of adjacent vertices belonging to the same class and all the arcs between a pair of color classes have the same orientation.

Analogues of cliques for oriented coloring [PDF]
Considered are subgraphs of oriented graphs in the context of oriented colouring that are analogous to cliques in traditional vertex colouring. Bounds on the sizes of these subgraphs are given for planar, outerplaner and series-parallel graphs. The authors show, among other things, that a planar graph cannot contain an induced subgraph \(D\) with more ...

Competitive Colorings of Oriented Graphs [PDF]
Nešetřil and Sopena introduced a concept of oriented game chromatic number and developed a general technique for bounding this parameter. In this paper, we combine their technique with concepts introduced by several authors in a series of papers on game chromatic number to show that for every positive integer $k$, there exists an integer $t$ so that ...

Linear choosability of graphs [PDF]
A proper vertex coloring of a non oriented graph $G=(V,E)$ is linear if the graph induced by the vertices of two color classes is a forest of paths. A graph $G$ is $L$-list colorable if for a given list assignment $L=\{L(v): v∈V\}$, there exists a proper

Generalized colorings and avoidable orientations [PDF]
This paper initiates the study of characterizations for the existence of generalized graph colorings in terms of avoidable orientations. If \({\mathcal P}_1,\dots ,{\mathcal P}_k\) are families of graphs, a \(({\mathcal P}_1,\dots , {\mathcal P}_k)\)-coloring of a graph \(G\) is a partition of the vertex set of \(G\) into \(k\) subsets \(V_1,\dots ,V_k\
