Possibly the links below could be added to a talk page and one could attempt to understand how, possibly mathematically, collaboration may influence on such equilibrium hypothesis ?

A version of the Nash equilibrium concept was first used by Antoine Augustin Cournot in his theory of oligopoly (1838). In Cournot's theory, firms choose how much output to produce to maximize their own profit. However, the best output for one firm depends on the outputs of others. A Cournot equilibrium occurs when each firm's output maximizes its profits given the output of the other firms, which is a pure strategy Nash Equilibrium.

http://en.wikipedia.org/wiki/Cournot_equilibrium

It has the following features:

There is more than one firm and all firms produce a homogeneous product, i.e. there is no product differentiation;

Firms do not cooperate, i.e. there is no collusion;

Firms have market power, i.e. each firm's output decision affects the good's price;

The number of firms is fixed;
Firms compete in quantities, and choose quantities simultaneously;
The firms are economically rational and act strategically, usually seeking to maximize profit given their competitors' decisions.
