Title:A fractional-order hyper-chaotic economic system with transient chaos Author(s):YOUSEFPOUR, Amin; JAHANSHAHI, Hadi; MUNOZ-PACHECO, Jesus M.; BEKIROS, Stelios D.
; WEI, ZhouchaoDate:2020Citation:
- Chaos Solitons & Fractals, 2020, Vol. 130, Art. 10940, OnlineOnly
Type:ArticleAbstract:We introduce for the first time a fractional-order hyperchaotic economic system. In this system, chaos generation depends upon the value of fractional-order. For certain fractional orders, a sustained regime of chaos is ...
