Graph theoryExtremal problems (MathematicsIn this chapter we study how global parameters of a graph, such as its edge density or chromatic number, can influence its local substructures. How many edges, for instance, do we have to give a graph on n vertices to be sure that, no matter how ...
Based on my lecture given there, I shall survey those parts of Extremal Graph Theory that are connected most directly with Paul Erdős’s work. In Turán type extremal problems we usually have some sample graphs L1,…,Lr, and consider a graph G n on n vertices not containing any L i ...

A graph is d-regular if all vertices have degree d. In the family of d-regular graphs of the same size, which graph has the largest number of independent sets? This ques- tion was initially raised by Andrew Granville in connection to combinatorial number theory and appeared first in print...
