Where: Seminario I, Dept. of Mathematics, Università di Bologna
Who: Francesco Cellarosi (Queen’s University, Canada)
What: Seminar “Recent progress towards Sarnak’s and Chowla’s Conjectures”
Abstract: I will present an overview of Sarnak’s conjecture on the disjointness of the Möbius function from any deterministic sequence and the related Chowla’s conjecture on the self-correlations of the Möbius function. Some progress towards weaker versions of these conjectures have been made recently, and I plan to illustrate them.

“AN INTEGRABLE BILLIARD CLOSE TO AN ELLIPSE OF SMALL ECCENTRICITY IS AN ELLIPSE”
Abstract: In 1927 G. Birkhoff conjectured that if a billiard in a strictly convex smooth domain is integrable, the domain has to be an ellipse (or a circle). The conjecture is still wide open, and presents remarkable relations with open questions in inverse spectral theory and spectral rigidity.

“On recent results of extreme value theory applied to dynamical systems”
Abstract: We give a review of a few recent results of extreme value theory applied to random dynamical systems and to coupled lattice maps.
Our beloved biennal workshop, currently titled DinAmicI IV, Fourth Workshop of the Italian Dynamicists, will take place in Corinaldo from Monday the 22th through Thursday the 25th of June 2015.
