In the background is a metaphysical question: what is a cycle?

An Experimental Investigation of Price Dispersion and Cycles 

------ Daniel Friedman (2020)

回顾十年

2010年,  TASP，No Cycle；

2010年,  2x2 matrix Selten game, Exists cycle;

2012年,  ONeill Game and angular momentum, Binmore experiment, Exists cycle;

2013年,  RPS,  Exist cycle; TASP Exists cycle. 

2014年,  RPS,  Exist cycle, Disregarding the stability;

2014年,   2x2 Eigenvalue and frequence of ycle; 

2017年,   Test models with velocity field, angular momentum

2020年,   Fine structure in high dimensional ONeill game;

2020年,  Price cycle and queation comes back to "a metaphysical question: what is a cycle?"

哲学问题

Dan,  In a chaostic trajactory, is there cycle?

Zhijian, between any two points, whenever a net current exists, cycle exists. 

结果

Game dynamics theory, on its reality and accuracy, become handlable during 2010-2020, but remains in two dimension level.  Dan and Zhijian do not reach an agreemant on the metaphysical question
