SUMMARY:CMSA/Tsinghua Math-Science Literature Lecture: Martin Bridson: Profinite rigidity: Chasing finite shadows of infinite groups
DESCRIPTION:CMSA/Tsinghua Math-Science Literature Lecture \n \nDate: March 10\, 2026 \nTime: 8:45 – 10:15 am ET \nLocation: Harvard Science Center Hall A\, 1 Oxford Street\, Cambridge MA &  via Zoom Webinar \nSpeaker: Martin Bridson FRS is the Whitehead Professor of Pure Mathematics at Oxford and President of the Clay Mathematics Institute. \nTitle: Profinite rigidity: Chasing finite shadows of infinite groups \nAbstract: There are many situations in geometry or elsewhere in mathematics where it is natural or convenient to explore infinite groups of symmetries via their actions on finite objects. But how hard is it to find these finite manifestations and to what extent does the collection of all such actions determine the infinite group?\nIn this talk\, I will sketch some of the rich history of such problems and then describe some of the significant advances in recent years. \nWe’ll pay particular attention to groups that arise in 3-dimensional geometry and topology. \n  \n\nBeginning in Spring 2020\, the CMSA began hosting a lecture series on literature in the mathematical sciences\, with a focus on significant developments in mathematics that have influenced the discipline\, and the lifetime accomplishments of significant scholars. \n  \n
