Abstract
The object of this paper is to present new theorems on the differentiability of a minimum, maximum, Min Max, or saddle point with respect to a parameter t ⩾ 0 at t = 0 under relaxed assumptions. Those technical results have a wide spectrum of applications: Control Theory, Shape Sensitivity Analysis, Game Theory, etc... In non-differentiable situations they provide an interesting description of the non-differentiability
