The goal of this paper is twofold. Firstly a short proof of the unicity of the reduced form of a normal form game is provided, using a technique to reduce a game originally introduced by Mertens. Secondly a direct combinatorial-geometric interpretation of the reduced form is described. This...

In this paper it is shown how to compute stable sets, defined by Mertens (1989), inthe context of bimatrix games only using linear optimization techniques.
