Two types of KAM-nondegenerate nearly integrable systems with positive metric entropy D. Chen Pennsylvania State University |

Abstract: The celebrated KAM Theory says that if one makes a small perturbation of a non-degenerate completely integrable system, there is still an overwhelming measure of invariant tori with quasi-periodic dynamics in the perturbed system. These invariant tori are known as KAM tori. What happens outside KAM tori draws a lot of attention. In this talk I will present two types of Language: English |
