Our colloquium takes place on the first Tuesday of each month from 15:30 to 16:30, usually in room A709.
A renowned expert (being an excellent speaker as well) visits us for an afternoon and gives a panorama of one of her research areas. The talk is meant to be accessible to all members of the lab, including PhD students in analysis, game theory, probability and statistics. Ideally, it should start gently with an historical background on the problem and an overview of the main questions and applications, keeping a non technical style during at least the first half of the talk. Of course it is also nice to have a part with more mathematical details: the most appreciated colloquia were those in which the speaker succeeded to develop a nice technical idea or an elegant argument that everyone should know.
Food and drinks are served after the event, usually in Espace 7!

Title: Fun with Fredholm determinants.
Abstract: Throughout my career, I have found Fredholm determinants to be a very powerful tool in the study of spectral theory and integrable systems. I would like to begin by explaining what they are and how I have used them, before pivoting to a recent nasty surprise and how forthcoming joint work with Yilun Wu and Monica Visan has restored my faith in Fredholm determinants.
