报告题目：Isoperimetric Inequalities and Geometric Measures

报告摘要：The classical isoperimetric problem is to determine a plane figure of the largest possible area with boundary of a given length and it was known in Ancient Greece. The first mathematically rigorous proof was obtained only in the 19th century by Weierstrass based on works of Bernoulli, Euler, Lagrange. Recent applications to Minkowski problem reveals connections between geometric measures and isoperimetric inequalities of convex bodies. We will discuss some applications based on some joint works with N. Fang, W. Xu and B. Zhu.
