Persistence of invariant graphs for twist maps under analytic perturbations
Qi Li, Yi Liu, Lin Wang
We consider the persistence for invariant graphs of twist maps that exhibit the strongest possible dynamics, namely those real-analytically conjugate to rigid rotations, under Gevr…

On the Dynamics of Invariant Graphs for Dissipative Twist Maps
Qi Li, Lin Wang
For two-parameter families of dissipative twist maps, we investigate the dynamics of invariant graphs as well as the thresholds for their existence and breakdown. Our main results…
