Aims
To provide basic notions and main tools in the field of mathematical economics: multivalued analysis, maximal elements, eqilibrium points. To use these tools in the theory of equilibrium of an abstract economy.
Content
1. Description of an economy. Arrow-Debreu model.
2. Multi-valued operators and fixed points for single-valued and multi-valued mappings.
3. KKM theory and variational inequalities. Optimal preferences.
4. Walrasian equilibrium of an economy.
5. Elements of game theory.
