Abstract:

The study of the 4-cycle has an important enlightening effect on the development of Turan type problems, especially the degenerate cases. In this talk, we focus on two conjectures about 4-cycles: a conjecture of Erdos on the upper bound of the Turan number ex(n,C_4), and a conjecture of Erdos-Simonovits on the supersaturation problem of 4-cycles. Joint with Tianchi Yang.
