These maps are characterized by a highly dispersed behavioral nature that reaches the extreme of robust chaos as a result of the border collision bifurcations that occurs especially in this type of mapsenBifurcations collision de la frontière, applications lisse par morceaux, comportement chaotiqueBorder collision bifurcations, piecewise smooth map, chaotic behaviorتشعبات تصادم الحدود، التطبيقات الناعمة المعرفة بالأجزاء، سلوك فوضوي.Thesis
