WebThe simplest area preserving map of the plane is the quadratic H´enon map [8]: (x,y) → (y+1− ax2,x), (1) where ais a parameter. Despite its simplicity, the area preserving H´enon map exhibits a very complex dynamics, described in a long list of papers appeared during the thirty years from its deﬁnition. WebThe standard map is one of a class of maps called ‘area-preserving twist maps’; it also has a number of symmetries, the most important of which is a time-reversal symmetry (see x6). The map (1) has a single parameter, k, that represents the strength of the non-linearity. A number of physical systems can be modeled by this map. One is solid surface cross reference color chart
