Second order optimality conditions and their role in PDE control
E Casas, F Tröltzsch - Jahresbericht der Deutschen Mathematiker …, 2015 - Springer
If f:R^n→R is twice continuously differentiable, f′(u)= 0 and f ″(u) is positive definite, then u
is a local minimizer of f. This paper surveys the extension of this well known second order …
