MSI Colloquium 2017
Each Thursday afternoon a distinguished academic presents his or her research via our colloquia events.
No events are currently scheduled.
Groupoids and Algebroids in Geometric Analysis »
I will show with many examples how Lie groupoids and Lie algebroids appear and how they are used in geometric analysis, particularly in index theory.
A few questions in the metric analysis of Banach spaces »
In the last fifteen years, the question of embedding metric spaces into “nice” Banach spaces has gathered researchers coming from very diverse origins.
The heat flow for harmonic maps and applications »
In 1964, Eells and Sampson asked whether a given smooth map can be deformed to a harmonic map in its homotopy class.
Undergraduate Colloquium: what is functional analysis about? »
In order to adapt them to infinite dimensional vector spaces, a whole new theory needed to be developed.
Population genetics stochastic process models forward and backward in time »
This talk will discuss examples of forwards and backwards in time models.
On the structure of optimal martingale transport plans in general dimensions »
I will describe the profile of optimal solutions of the martingale counterpart of the Monge mass transport problem.
A Primal Dual Active Set Algorithm for Sparse Reconstruction Problems »
In this talk, we consider the problems of recovering a sparse vector from noisy measurement data.
Recent development on the long time behaviour to some quadratic dispersive systems »
In this talk I will survey some recent results on the study of the long time behaviour to some quadratic dispersive systems such as Zakharov system and Gross-Pitaevskii equation.
Subfactors and Quantum Symmetry »
In this talk, we will explain how symmetries of inclusions of operator algebras can be described in the language of tensor categories.
Spectral gaps and the fractal uncertainty principle »
This talk is based on joint works with Jean Bourgain, Long Jin, and Joshua Zahl.
Polygonal billiards, flat surfaces, and translation flows: to infinity and beyond »
In this talk, I will survey the origins of the field, state some classical results, and mention some recent efforts to develop the theory further to include surfaces of infinite type.
Unlikely Intersections in Algebraic Dynamics »
The goal of the talk is to give an overview of some results about algebraic and geometric structures in orbits of polynomial dynamical systems.
