Title : On the dynamics of rational maps
Time : 2020-05-20 (Wed) 13:30 - 15:30
Place : Seminar Room 617, Institute of Mathematics (NTU Campus)
Abstract: We will first introduce the basic notions of arithmetic dynamics of rational maps and some open questions of unlikely intersections in this setting. Then we will show how to construct elliptic curves with large intersection of projective torsion points (equivalently, Lattès maps with large intersection of preperiodic points). If time allows, we will also discuss the potential-theoretic approach, which has been widely used to deal with such problems.
