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.
