Is it true that a Cournot game with two firms results in a unique symmetric Nash equilibrium under standard cost conditions?

Yes. Standard economic theory and literature support the premise that a standard Cournot duopoly game yields a unique symmetric Nash equilibrium under appropriate cost and demand conditions.
