摘要: In this talk, I will first introduce the famous unsolved slicing problem by Bourgain in details. Then I will address our recent work on the extremal sections of convex bodies. Bounds for the volume of sections of convex bodies which are in the Lp John ellipsoid positions are established. Specifically, when the convex bodies are in the LYZ ellipsoid position, we construct a family of Hanner polytopes, which indeed attain the sharp bounds. This talk is based on the joint work with Jiangyan Tao and Ge Xiong.
