Jointly convex quantum Jensen divergences
Dániel Virosztek
We investigate the quantum Jensen divergences from the viewpoint of joint convexity. It turns out that the set of the functions which generate jointly convex quantum Jensen diverge…

Applications of an intersection formula to dual cones
Dániel Virosztek
We give a succinct proof of a duality theorem obtained by Révész in 1991 which concerns extremal quantities related to trigonomertic polynomials. The key tool of our new proof is a…

Maps on positive definite operators preserving the quantum -divergence
Hong-Yi Chen, György Pál Gehér, Chih-Neng Liu +3
We describe the structure of all bijective maps on the cone of positive definite operators acting on a finite and at least two-dimensional complex Hilbert space which preserve the…
