General simultaneous N player games.

4.6.3. The Kalai-Smorodinsky solution.
Tema 5
A brief introduction to sequential games with imperfect information: the idea of forward induction.
Tema 6
More on mechanism design.
Tema 7
Matching.
Tema 8
Cooperative game theory.
8.1. Games in characteristic form.
