报告摘要:
In 1972, Chvátal conjectured that every hereditary family of finite sets has a largest intersecting subfamily that is a star. Despite its simple statement, the conjecture remained open for over fifty years. In this three-lecture series, I will introduce the background and motivation for the conjecture and explain its recent proof, based on joint work with Fan Chang and Miao Liu. The lectures will focus on the main ideas behind the proof, in particular the role of a sharp correlation inequality.
