If f g F(X) are super modular, then f g is super modular f is super modular for every 0 Therefore the set of all super modular functions on a set X is a cone in F(X)

Question: If f; g F(X) are super modular, then f g is super modular f is super modular for every

If f; g ∊ F(X) are super modular, then
• f g ∊ is super modular
• αf is super modular for every α ≥ 0
Therefore the set of all super modular functions on a set X is a cone in F(X).
