WebFeb 1, 2024 · The dynamics of a two dimensional area-preserving (or symplectic) map is a very interesting classical subject that has been studied extensively in the literature (see for example in [1,2,3,4]). One of the key results is the existence of quasi-periodic motions on invariant curves in the neighbourhood of an elliptic fixed point. WebArea-preserving maps also arise in the study of the motion of Lagrangian tracers in incompressible ﬂuids or of particles tightly gyrating around magnetic ﬁeld lines. In particular, when one component of the ﬁeld is particularly strong, such as in the plasma device called a tokamak, the transverse dynamics reduces to an area-preserving map. on the buses on youtube
