Résumé:
The main goal of this thesis is to investigate different kinds of
bifurcations in some 2-D Zeraoulia-Sprott chaotic discrete
mappings. It exoplores the normal form of these systems, the
various kinds of bifurcations, and the conditions under which they
occur. the study also inverstigates chaos and bifurcation
phenomena in both the modified Lozi and Logistic systems
highlighting the main characteristics of each system.
