报告摘要: The classical Birkhoff conjecture states that if the plane billiards inside a closed smooth convex curve is integrable then the curve is an ellipse. In higher dimensions, all known integrable billiards are inside billiard tables consisting of pieces of quadrics. We study Birkhoff billiards in convex cones in Rn and prove that billiards in any C3-smooth convex cone are integrable. This provides the first examples of integrable billiard tables in Rn not related to quadrics.
