Query: Maps on positive definite matrices preserving Bregman and Jensen
  divergences   In this paper we determine those bijective maps of the set of all positive
definite $n\times n$ complex matrices which preserve a given Bregman divergence
corresponding to a differentiable convex function that satisfies certain
conditions. We cover the cases of the most important Bregman divergences and
present the precise structure of the mentioned transformations. Similar results
concerning Jensen divergences and their preservers are also given.
