Abstract: In this paper, we show the proof that if profit function has two liner isoprofit curves the profit function is quadratic and polynominal with degree two. And we show that if the profit function is quadratic the profit function has two liner isoprofit curves. This lemma over isoprofit curves of duopoly games assert there cannot be any mixed strategy equilibria when the equilibrium with simultanious move is stable.
