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. WebThis map was ﬁrst proposed by Bryan Taylor and then independently obtained by Boris Chirikov to describe the dynamics of magnetic ﬁeld lines. The standard map and …
