The authors generalize several theorems in convex analysis (Ky Fan's inequality, saddle point theorem) and quasi-variational inequalities by using weaker convexity (concavity) conditions. These conditions require a functional \(\Phi(x,y)\) to be (quasi-) convex for diagonal entries of certain type.
