Welcome to our series of online seminars aimed at an accessible presentation of some of the most significant mathematical theorems of the 21st century.
Schedule and Speakers: You can find the schedule of upcoming talks here. We are proud to host an impressive list of speakers featuring world-renowned mathematicians.
What to Expect: Each talk will cover the background, definitions and formulation of a particular theorem as well as its historical context and subsequent developments. Where possible, speakers will also provide a brief, non-technical overview of the proof.
Who Should Attend: The talks will appeal to those who enjoy the beauty of mathematics. These talks are aimed at a wide mathematical audience, including professional mathematicians, graduate students, and undergraduate mathematics students approaching the end of their degree. The only prerequisite is a training in mathematics to an undergraduate level and, for some talks, even this is not required.
How to Join: Each talk listed in the schedule includes a direct participation link. To join, simply click on the link at the scheduled time, enjoy the presentation, and feel free to ask questions. No prior registration is required.
Mailing List: To make sure you don’t miss any forthcoming talks, please consider joining our seminar mailing list. Once you join, you will receive one email per month with the schedule of upcoming talks and a list of the confirmed future speakers. To join the mailing list, please email the seminar organizer, Bogdan Grechuk, at [email protected] , or enter your name and e-mail here.
Previous talks: We record the talks and make them available online on the seminar YouTube channel shortly after the live event. You can access the archive of previous talks and their corresponding recordings here.
Want to find out more?: This seminar series is devoted to explaining significant theorems in an accessible format. You can find descriptions of more such theorems in this book (covering period 2001-2010) and this book (covering 2001-2020).
