On General Minimax Theorems

Authors: Maurice Sion

Published: 1958 (Journal Paper)

Algorithm: Sion Minimax Theorem

Summary

Proves a generalization of von Neumann's minimax theorem to quasi-convex/quasi-concave functions on compact convex sets in topological vector spaces, without requiring the sets to be finite-dimensional. The Sion minimax theorem is a foundational result in game theory and saddle-point optimization.
