 Von Neumann's theorem

Von Neumann's theorem can refer to different results in various fields of mathematics and economics, depending on the context. Here are two prominent examples: 1. **Von Neumann's Minimax Theorem**: In game theory, this theorem, established by John von Neumann, states that in a two-player zero-sum game, there exists a value (the minimax value) that represents the optimal outcome for both players, assuming each player plays optimally.
