Take the 2-minute tour ×  Suppose that $K_{1}$ and $K_{2}$ are
pointed closed cones in a finite-dimensional space $V$ whose
Hilbert metrics $d_{1},d_{2}$ are known. Is there a way to
express the Hilbert metric of $K_{1}+K_{2}$ in terms of $d_{1}$
and $d_{2}$?  share|improve this question Do you mean the
Hilbert projective metric? –  Suvrit Sep 30 '13 at 14:20 What
exactly do you mean by "the Hilbert metric"? –  Rami Oct 3 '13
