Title: Complex dynamics and elliptic curves

Abstract:
In this talk, I will explain some connections between recent research in dynamical systems and the classical theory of elliptic curves and rational points. I will begin with the theorem of Mordell and Weil from the 1920s, presented from a dynamical point of view. I will continue by describing a dynamical/geometric proof of a result of Masser and Zannier about torsion points on elliptic curves and “unlikely intersections”. Finally, I aim to explain the role of dynamical stability and bifurcations in finiteness statements.
