Alice Roth Lecture 2022
It is with great pleasure we announce Professor Maryna Viazovska as the keynote speaker of the 2022 Alice Roth Lecture.
Maryna Viazovska:
Fourier interpolation pairs and their applications
Maryna Viazovska is a full professor and Chair of Number Theory at EPFL. Viazovska completed her Bachelor's degree at the Kyiv National Taras Shevchenko University and graduated with a Master's degree at the Technical University of Kaiserslautern. In 2013 she obtained her doctoral degree in Bonn followed by postdoctoral positions at the Institut des Hautes Etudes Scientifiques and the Humboldt-Universität zu Berlin. In 2017, Viazovska was Distinguished Visitor at Princeton University. She joined EPFL as a tenure-track assistant professor in 2017 and was appointed full professor in 2018. In autumn 2020, she received the Latsis prize for her solution to a centuries-old problem about the optimal arrangement of spheres in a defined space and in 2022 she was awarded the Fields Medal.
Abstract
This lecture is about Fourier uniqueness and Fourier interpolation pairs, some explicit constructions of such pairs and their applications. Suppose that we have two subsets X and Y of the Euclidean space. Can we reconstruct a function f from its restriction to the set X and the restriction of its Fourier transform to the set Y? We are interested in the pairs (X,Y) such that the answer to the question above is affirmative. In this talk I will give an overview of recent progress on explicit constructions and existence results for Fourier interpolation pairs and corresponding interpolation formulas. Also I will try to convince you that explicit Fourier interpolation is a useful gadget in solving optimization problem and analysing differential equations.
Inaugural ceremony
The 2022 Alice Roth evening lecture marked the start of this new series. On this occasion, there was a short introduction to the life and work of Alice Roth before the main lecture by Maryna Viazovska.
The recording of the Alice Roth lecture can be found on the ETH video portal.
