In 1960 Berge came up with the concept of perfect graphs, and in doing so, conjectured some characteristics about them. A perfect graph is a graph in which the chromatic number of every induced subgraph equals the size of the largest clique of that subgraph [2]. Two conjectures are now known as the Perfect Graph Theorem and the Strong Perfect Graph Theorem. Both of these theorems make detemining if a graph is perfect much easier than using the standard definition. Simply looking at any graph… 

Improved Algorithms for Recognizing Perfect Graphs and Finding Shortest Odd and Even Holes

Improved algorithms for detecting or finding induced subgraphs in G, a graph that can be obtained by deleting a set of vertices together with its incident edges, are shown.

Colouring perfect graphs with bounded clique number

Defective coloring is perfect for minors

The defective chromatic number of a graph class is the infimum k such that there exists an integer d such that every graph in this class can be partitioned into at most k induced subgraphs with

The Strong Colors of Flowers - The Structure of Graphs with Chordal Squares

A proper vertex coloring of a graph is a mapping of its vertices on a set of colors, such that two adjacent vertices are not mapped to the same color. This constraint may be interpreted in terms of

χ‐bounded families of oriented graphs

It is proved that for any oriented star S, every oriented graph with sufficiently large chromatic number contains either a transitive tournament of order 3 or S as an induced subdigraph.

Colouring graphs with no induced six-vertex path or diamond

This paper shows that the chromatic number of a (P 6, diamond)-free graph G is no larger than the maximum of 6 and the clique number of G, and shows that there is exactly one 6-vertex-critical (P6, diamond, K6)- free graph.

Cliques, stable sets, and coloring in graphs with forbidden induced subgraphs

The Gyárfás-Sumner conjecture [29, 42] states that for every tree T , there is a function f such that for every graph G with no induced subgraph isomorphic to T , the chromatic number of G is at most

M2 Internship Report Structure of Even-Hole-Free Graphs

An even-hole-free graph is a graph that has no induced even cycles of length at least 4. This class is structurally similar to the class of perfect graphs, which was one initial motivation for their

Coloring ($P_5$, kite)-free graphs

Let P n and K n denote the induced path and complete graph on n vertices, respectively. The kite is the graph obtained from a P 4 by adding a vertex and making it adjacent to all vertices in the P 4

Submodular functions and perfect graphs

We give a combinatorial polynomial-time algorithm to find a maximum weight independent set in perfect graphs of bounded degree that do not contain a prism or a hole of length four as an induced
