Center node: "metrics induced by quantum jensen shannon renyi and related divergences"
  Abstract: We study symmetric divergences on Hermitian positive definite matrices generated by functions closely related to Pick-Nevanlinna functions. Our main result proves that the square root of these divergences is a distance metric. As a corollary we obtain the metric property for Quantum Jensen-Shannon-Tsallis divergences (parameterized by $\alpha\in [0,2]$), which in turn (for $\alpha=1$) yields a proof of the metric property conjectured by Briet and Harremoes a decade ago (\emph{Properties of classical and quantum Jensen-Shannon divergence}, Phy.\ Rev.\ A, \textbf{79}, 052311 (2009)). A somewhat more intricate argument also establishes metric properties of Jensen-Renyi divergences (for $\alpha \in (0,1)$), and outlines a techniques for proving this property for symmetric divergences involving completely monotonic functions.
