报告摘要:The spectral theory of quasiperiodic operators is a fascinating field which continuously attracts a lot of attentions for its rich background in quantum physics as well as its rich connections with many mathematical theories and methods. In this talk, I will briefly introduce the problems in this field and their connections with dynamical system. I will also talk about some recent results joint with Avila, Ge, Leguil, Zhao and Zhou on both spectrum and spectral measure by reducibility theory in dynamical systems.
报告人简介:尤建功,南开大学陈省身数学研究所教授、博士生导师。2000年成为国家重点基础研究发展规划项目组(非线性科学)成员。在Duffing方程的稳定性,KAM理论,哈密顿偏微分方程的拟周期运动、薛定谔算子的谱理论等方面做出了一系列深刻的工作。2018年8月1日至8月9日,第28届国际数学家大会于在巴西里约热内卢召开,尤建功教授应邀参加第28届国际数学家大会并于2日作45分钟特邀报告,继龙以明院士、张伟平院士之后,南开学者又一次应邀在国际数学家大会上作主题报告。
