1 теорема о неподвижной точке
Наиболее распространенная в экономике методика установления существования решений равновесной системы уравнений заключается в постановке проблемы как поиска неподвижной точки построенной соответствующим образом функции или соответствия. Причина следования этим, часто обходным путем заключается в том, что важные математические теоремы для доказательства существования неподвижных точек легко доступны. — In economics the most frequent technique for establishing the existence of solutions to an equilibrium system of equations consists of setting up the problem as the search for a fixed point of a suitably constructed function or correspondence. The reason for proceeding in this, often roundabout, way is that important mathematical theorems for proving the existence of fixed points are readily available.
