This post is a small exploration of the A model balancing cooperation and competition can explain our right-handed world and the dominance of left-handed athletes.

I explore the model:


where l(t) is the fraction of left handers in the population and  the cooperation and competitve (sigmoid) functions used are from another paper by the same authors.


The dynamics are explored for some values of cooperative function, coupling constant:


Critical points: red dl/dt>0, dl/dt>0:



and exploration with varying initial population of left handers showing pitchfork bifurcation behaviour:



This is a very interesting paper. Perhaps, other people will enjoy it.
