Obiective | Aims |
Asimilarea de catre studenti a unor notiuni si tehnici de lucru din teoria operatorilor univoci si multivoci (teoreme de punct fix, teoreme de elemente maximale, teoreme de coincidenta, teoreme de selectie) si utilizarea lor in rezolvarea unor probleme matematice provenind din economie: echilbru preturilor,problema consumatorului,echilibru unei economii abstracte. |
To provide basic notions and main tools in the field of mathematical economies: multivalued analysis, maximal elements, eqilibrium points. To apply these tools in the theory of equilibrium of an abstract economy.
