Speaker: Professor Asuka Takatsu, Tokyo Metropolitan University
Title: Curvature and Optimal transport
In this series of lectures, I first review the notion of curvature (Gaussian curvature and Ricci curvature).
In particular, I recall some comparison theorems (Toponogov's triangle comparison theorem, Bishop--Gromov volume comparison theorem etc).
Then I introduce a generalized notion of curvature in non-smooth spaces.
Speaker: Professor Jun Kitagawa, Michigan State University
Title: A brief introduction to branched optimal transport
The optimal transport (also known as Monge-Kantorovich) problem is a classical optimization problem which has recently become the focus of much research with connections to various fields such as PDEs, geometry, and applications. In particular, it provides an effective way to metrize the space of probability measures on a given metric space. However, there is an alternate approach to metrizing such spaces using so called branched optimal transport. Branched optimal transport is based on the classical Gilbert-Steiner problem, later adapted by Qinglan Xia, and in contrast to the Monge-Kantorovich approach tends to yield branching structures. In this series of lectures I will introduce the basics of branched optimal transport and discuss some of the known results in the literature.

The World Quantum Day is obviously celebrated on April 14, as 4.14 are the rounded first digits of Planck’s constant (in units of eV.s). It aims at engaging the general public in the understanding and discussion of Quantum Science and Technology around the world.This year’s launch event is a presentation by Prof. Alain Aspect (Institut d’Optique Graduate School, Université Paris-Saclay) on one of the fundamental mysteries of quantum mechanics: the duality between waves and particles.
We invite you to watch Prof. Aspect’s presentation (and join a discussion) on Thursday, April 15th at 1pm in B250 (new normal rules and regulations apply).
Audience: General public
