Awesome graph parameters
Abstract
For a graph , we denote by the size of a maximum independent set and by the size of a maximum clique in . Our paper lies on the edge of two lines of research, related to and , respectively. One of them studies -variants of graph parameters, such as -treewidth or -degeneracy. The second line deals with graph classes where some parameters are bounded by a function of . A famous example of this type is the family of -bounded classes, where the chromatic number is bounded by a function of . A Ramsey-type argument implies that if the -variant of a graph parameter is bounded by a constant in a class , then is bounded by a function of in . If the reverse implication also holds, we say that is awesome. Otherwise, we say that is awful. In the present paper, we identify a number of awesome and awful graph parameters, derive some algorithmic applications of awesomeness, and propose a number of open problems related to these notions.
