The geometry of a stable game
Martin Griffiths · The Mathematical Gazette · 2011
I was prompted to write this article after two of my students came to me (independently) with what was essentially the same query. This concerned the graphical solutions of a particular scenario occurring in Game Theory. In order to state and then fully to understand their question we need to make a little foray into this area of mathematics, which appears as one of the topics in the Decision 2 module of the OCR A level (see [1], for example).
