A Variant of the Log Brunn-Minkowski Inequality题目:A Variant of the Log Brunn-Minkowski Inequality报告人:蒋美跃 教授 (北京大学)时间:2023年6月6日 15:05-16:05地点:腾讯会议室摘要Let K,L be symmetric convex bodies in R^n; h_K, h_L be the support functions of K,L, respectively, the following log Brunn-Minkowski inequality conjecture was proposed by Boroczky-Lutwak-Yang-Zhang (Adv. Math. 2012).∫_(S^(n-1))〖log h_L/h_K 〗dV_K≥V(K)/n log V...蒋美跃 教授 (北京大学)腾讯会议室2023年6月6日 15:05-16:05

Riemannian Metrics with Prescribed Finite Parts of Spectra题目:Riemannian Metrics with Prescribed Finite Parts of Spectra报告人:王作勤 教授 (中国科学技术大学)时间:2023年5月30日 16:30-17:30地点:致远楼101室摘要:In 1980s Colin de Verdiere proved that on any closed manifold of dimension at least 3, one can construct a smooth metric with arbitrarily prescribed finite parts of eigenvalues. Later on Lohkamp showed that one can further prescribe the vo...王作勤 教授 (中国科学技术大学)致远楼101室2023年5月30日 16:00-17:00
