Abstract:

The Henon and Lozi maps are among the most widely used in physics applications due to their ability to generate two chaotic attractors for specific values of their bifurcation parameters. In this study, I propose a new 2D smooth piecewise quadratic map created by merging the two maps. We demonstrate that this map exhibits both strong and fragile chaotic behavior for varying values of the bifurcation parameters a and b. The new map reveals distinct chaotic attractors, displaying both strong and fragile chaos for certain values of these parameters. Consequently, this map produces two chaotic attractors one fragile and the other strong highlighting the rich diversity of dynamic behavior.

Abstract:

In this paper, we study the Lozi map by replacing the piecewise linear term in the first equation by the function max (f(x,y);g(x,y)) such that f and g are two arbitrary functions in R². This is a family model that allows us to study several new piecewise-smooth maps. We demonstrate that these models converge to a robust chaotic attractor and give some applications of these models in the real world.
