WebJun 1, 2015 · The conflict network game satisfies the requirement of a concave n-person game by the assumptions on the payoff function. Hence, the following proposition establishes existence and uniqueness by proving that the conflict network game is also diagonally strictly concave. Proposition 1 There exists a unique equilibrium in the … WebWe say that a graph is concave up if the line between two points is above the graph, or alternatively if the first derivative is increasing. (In finance, such a curve is said to be convex.) Similarly, we say that a graph is concave down if the line between two points is below the graph, or alternatively if the first derivative is decreasing.

We say f is concave if −f is convex. An affine function is both convex and concave. A function f is convex if it is convex when restricted to any line intersecting its domain: for any x ∈ domf and v, g(x +tv) is convex on {t : x +tv ∈ domf}.

Web40 x 2 y − 10 − 64 x 2 y − 10 = − 24 x 2 y − 10 ⩽ 0 which means f ( x, y) is concave. Since f ( x, y) is nonlinear, it cannot be both convex and concave, and there must be something wrong with the derivation above. I would like to ask which part of my under standing is wrong.
