Sinister

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:

zleft02

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:

zleft03

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

zleft04

 

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

zleft01

 

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