Title  ζ(3), log 2 and π (Video Recording)


Values of the Riemann zeta function at odd positive integers have proved enigmatic over several centuries of study. In 1740, Euler asked whether ζ(3) could be expressed algebraically in terms of log 2 and π. In this talk, we shall show that the Grothendieck period conjecture applied to certain mixed motives answers Euler's question in the negative.

About the speaker

V Kumar Murty photo V. Kumar Murty received his doctorate from Harvard University in 1982 as a student of John Tate. In 1987, he was appointed Associate Professor at the University of Toronto, and in 1991 he was promoted to Full Professor. Twice he was Chair of the Department of Mathematics at the University of Toronto Downtown campus. He is currently the Director of the Fields Institute for Research in Mathematical Science.

Professor Murty's mathematical interests cover diverse areas including analytic number theory, algebraic number theory, information security, and arithmetic algebraic geometry. His recent work has expanded to mathematical modelling in social, economic and health contexts. This includes his work on Smart Villages and on integrative modelling related to the COVID-19 pandemic.

He has served on the Canadian Mathematical Society Board of Directors and held vice-presidency at the Canadian Mathematical Society. He was elected a Fellow of the Royal Society of Canada in 1995, Fields Institute Fellow in 2003, Fellow of the National Academy of Sciences (India) in 2011, Senior Fellow of Massey College in 2020 and a Fellow of the American Mathematical Society in 2021. He received the Coxeter-James Prize in 1991, the Balaguer Prize (together with M. Ram Murty) in 1996, and the University of Toronto's Inventor of the Year Award in 2011.
