Title : Complex Dynamics and Parabolic Implosion

Abstract :
In this talk, after a brief introduction to complex dynamics, I will present the phenomenon of parabolic implosion, which has been the subject of significant recent research in the field. I will aim to provide some intuition behind this phenomenon and explain why it plays such an important role. Parabolic implosion lies at the heart of complex dynamics, both in one variable and in several variables, and remains a fascinating area of study.

Title: The Brownian Mirror: from Pitman's Theorem to Representation Theory.

Abstract: We are going to do a bit of probability, we are going to do a bit of algebra, we are even going to play a little game, some sort of combinatorial "jeu de taquin". The common thread throughout will be Pitman’s Theorem, which states that a Brownian motion minus twice its running infimum is again a Markov process. What looks like a probabilistic curiosity turns out to hide a surprisingly deep algebraic and combinatorial structure.
