Tiivistelmä: | Fixed-point theorems for multi-valued mappings and economic equilibrium existence theorems are generalized from the viewpoint that the continuity and/or convexity assumptions on a mapping may be replaced by weaker local conditions on the vector field defined by the mapping. The generalization gives us natural conditions on individual preferences or aggregated demand behaviours so that we may obtain several extensions of recent results in social and game-theoretical equilibrium theories. |
