报告摘要 Abstract:
Duffing equations are important mathematical models in the theory of nonlinear dynamics and celestial mechanics. There are lots of mathematical tools on the boundedness and unboundedness for periodic cases. On the contrary, there is a lack of effective tools on the boundedness and unboundedness for non-periodic cases.
In this talk, we will introduce the non-periodic twist mappings’ theory established and developed by Kunze and Ortega in recent years. Furthermore, we will introduce how to use the above theory to study the boundedness and unboundedness of solutions for non-periodic equations.
