Proper efficiency results in vector optimisation in real linear-topological spaces based on vectorial penalisation
Paul Schmölling, Christian Günther, Christiane Tammer +1
In this paper, we are dealing with constrained vector optimisation problems where the objective function acts between real linear-topological spaces. Our aim is to study the relati…

Necessary conditions for approximate solutions of vector and set optimization problems with variable domination structure
Marius Durea, Christian Günther, Radu Strugariu +1
We consider vector and set optimization problems with respect to variable domination structures given by set-valued mappings acting between the preimage space and the image space o…

Nonlinear Strict Cone Separation Theorems in Real Normed Spaces
Christian Günther, Bahareh Khazayel, Christiane Tammer
In this paper, we derive some new results for the separation of two not necessarily convex cones by a (convex) cone / conical surface in real (reflexive) normed spaces. In essence,…
