Graph coloring

Oriented coloring

In graph theory, oriented graph coloring is a special type of graph coloring. Namely, it isan assignment of colors to vertices of an oriented graph that * is proper: no two adjacent vertices get the same color, and * is consistently oriented: if vertices and have the same color, and vertices and have the same color, then and cannot both be edges in the graph. Equivalently, an oriented graph coloring of a graph G is an oriented graph H (whose vertices represent colors and whose arcs represent valid orientations between colors) such that there exists a homomorphism from G to H. An oriented chromatic number of a graph G is the fewest colors needed in an oriented coloring;it is usually denoted by . The same definition can be extended to undirected graphs, as well, by defining the oriented chromatic number of an undirected graph to be the largest oriented chromatic number of any of its orientations.

Edge Colorings and Chromatic Index of Graphs | Graph Theory

We introduce edge colorings of graphs and the edge chromatic number of graphs, also called the chromatic index. We'll talk about k-colorings/k-edge colorings, minimum edge colorings, edge colourings as matchings, edge colourings as functions, and see examples and non-examples of edge color

Jesus De Loera: Tverberg-type theorems with altered nerves

Abstract: The classical Tverberg's theorem says that a set with sufficiently many points in R^d can always be partitioned into m parts so that the (m - 1)-simplex is the (nerve) intersection pattern of the convex hulls of the parts. Our main results demonstrate that Tverberg's theorem is b
