报告题目:Floating Bodies and Floating Functions

报 告 人: 李奔 博士

  位: 以色列特拉维夫(Tel  Aviv)大学

报告时间:2018913日(星期四10:00-11:00

报告地点:阳明学院303

报告摘要: In this talk I will firstly introduce  floating body  for convex bodies. It is a classical notion in affine convex geometry and closely related to another important notion affine surface area. Secondly, I will discuss the recent result on extending this notion to the setting of functions. We introduce floating functions and  establish the asymptotic behavior of the integral difference of a log concave function and its floating function. This gives rise to a new affine invariant which bears striking similarities to the Euclidean affine surface area. The latter result is based on the joint work with Carsten Schuett and Elisabeth Werner.
