Simplifying the computation of weak- second subderivatives of convex functionals via -convergence
Gerd Wachsmuth
We prove (under some mild assumptions) that the strong-strong twice epidifferentiability of a convex functional is equivalent to the weak- twice epidifferentiability of its…

Uniqueness and stability of Lagrange multipliers and associated qualification conditions
Patrick Mehlitz, Gerd Wachsmuth
This paper is concerned with uniqueness and stability of Lagrange multipliers for constrained optimization problems in abstract spaces. It is well known that validity of the strict…
