摘要：In this talk, we give proof of a famous conjecture of Hofer-Wysocki-Zehnder published in 2003 asserting that a smooth and autonomous Hamiltonian flow on R4 has either two or infinitely many simple periodic orbits on any regular compact connected energy level that is transverse to the radial vector field. This talk is based on my joint work with Cristofaro-Gardiner, Hryniewicz and Hutchings.
