Prof. Chen joined University of California, Merced in summer 2012. He is currently one of the leading researchers in the fractional order field, especially in fractional order system. He is an Associate Editor for IFAC journals of Mechatronics and Control Engineering Practice, Fractional Calculus and Applied Analysis, IET Control Theory and Applications, IEEE Transactions of Control Systems Technology, ISA Transactions and Cogent Engineering (Systems and Control). He also serves as the Topic-Editor-in-Chief in “Field Robotics” for International Journal of Advanced Robotic Systems (IJARS), a Senior Editor for International Journal of Intelligent and Robotic Systems, and an associate editor for Journal of Intelligent Service Robotics. Until now he has published over 10 research books and textbooks. He has more than 23000 Google Scholar citations with 67 H index. Fractional calculus (FC) is about differentiation and integration of non-integer orders. This tutorial talk is trying to promote the view point that, using FC based tools, we can understand complexities better. We start with basics on power law manifest of complexities and explain how power law is linked to fractional order dynamics. We highlight heavy-tailedness and long range dependence in connection to extreme events. “extreme events” are happening more and more often. What’s the governing law behind it? How we better understand it? Why this is linked to fractional order dynamics? Finally, the speaker will share an interesting interpretation of Taoism and the fact that, fractional calculus way of thinking was perhaps already embedded in the text of Lao Tzu’s “Tao Te Ching.” We shall end the talk by sharing how your research excellence could be enhanced or even enabled by using fractional order thinking suggested in this talk.
