comment Origin of the notation for statistical divergence
Sure, but why not use the notation D(P, Q), which is, you know, the default notation for a binary function?

comment Generalization of metric spaces
Not sure if I asked the question properly. Basically I'm wondering whether spaces where non-negativity and the "identity of indiscernibles" don't hold (of which subtraction of real numbers is an example) have been studied or are worth studying at all.

comment Generalization of metric spaces
$d(x,y) = 0$ iff $x = y$ would still work. I am unsure if an analog to the triangle inequality would work.
