In the mathematical area of game theory, a minimax theorem is a theorem providing conditions that guarantee that the max–min inequality is also an equality. The first theorem in this sense is von Neumann's minimax theorem about zero-sum games published in 1928, which was considered the starting point of … Ver mais The theorem holds in particular if $${\displaystyle f(x,y)}$$ is a linear function in both of its arguments (and therefore is bilinear) since a linear function is both concave and convex.
