Question 1. A Nash equilibrium strategy profile $s^{?}$ is a strict Nash equilibrium, if $v_i\left(s^{?}{s}_i{s}^{?}{}_{?i}\right)>v_i\left(s_i+s^{?}{}_{?i}\right)$ holds $?i?N$ and $?s_i?S_i$ with $s_i?=s^{?},{}^1$ Consider all the ganes we have covered in elass (prisoner s dileman, partanuship gane, rock-payer-sciksors game, battle of sexes, stag hunt, matching pennies, Cournot cotrpetition, Bertrand competition), and determine whether their Nash equilibria are strict or not.
