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. The analysis of multi-valued operators. 
3. Fixed point, sstrict fixed point and coincidence point theorems 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.
