Matrix-Test Duality: A Support-Function Characterization for -Convex Families of CP Maps
Mohsen Kian, Mario Krnic
We develop a matrix-test dual framework for -convex families of completely positive maps $\CP(\mathscr S,\mathscr T)$, where is an operator system and $\mathscr T…

Improved Jensen-type inequalities via linear interpolation and applications
Daeshik Choi, Mario Krnić, Josip Pecarić
In this paper we develop a general method for improving Jensen-type inequalities for convex and, even more generally, for piecewise convex functions. Our main result relies on the…
