报告内容: In extremal graph theory one is interested in the realtions between various graph invariants. Given a property P and an invariant u for a family F of graphs, we wish to determine the maximum value of u(G) among all graphs G in F satisfying the property P. The optimial value u(G) is called the extremal number and the graphs attaining this value are called extremal graphs. A principal example of such an extremal problem is the so-called Turan type problem, initiated by Hungarian mathematicians Turan and Erdos in 1940s.
In this talk, we will discuss some recent results on extremal graphs and a related conjecture of Erdos-Simonovits.
