Lattice Point Inequalities from Convex Geometry题目:Lattice Point Inequalities from Convex Geometry报告人:Martin Henk (Technische Universität Berlin)地点:致远楼101室时间:2024年11月5日 10:00-11:30摘要: In recent years, more and more discrete variants of classical inequalities from convex geometry, such as Brunn-Minkowski, have been investigated. The goal is, roughly speaking, to replace the volume functional in these classical inequali...Martin Henk (Technische Universität Berlin)致远楼101室2024年11月5日 10:00-11:30
