Barycenters and a law of large numbers in Gromov hyperbolic spaces
We investigate barycenters of probability measures on Gromov hyperbolic spaces, toward development of convex optimization in this class of metric spaces. We establish a contraction property (the Wasserstein distance between probability measures provides an upper bound of the distance between their barycenters), a deterministic approximation of barycenters of uniform distributions on finite points, and a kind of law of large numbers. These generalize the corresponding results on CAT(0)-spaces, u…

Neargeodesics in Gromov hyperbolic John domains in Banach spaces
In this paper, we prove that neargeodesics in Gromov hyperbolic John domains in Banach space are cone arcs. This result gives an improvement of a result of Li [Theorem 1, Int. J. Math. 25 (2014)].

This makes me want to cry.
Because I can’t count how often I’ve needed to point out to “software engineers” that they are NOT leaking memory and they do NOT need a bigger box, just because over time the total memory usage approaches 99%
One guy was so committed to not believing the #sysadmin that he ended up being fired for an over-reaction. I never wanted that but I‘m not the one who…

84°F, *dew point 72°F* in #Eastpointe #Michigan at 9AM.
It's a sort of humidity that just hits one in the face when stepping outdoors. https:…

The gentle walk around the lake today was breathtaking, and my knee was grumbling but OK, too.
This was our picnic spot, on Low Ling Crag.
