Fast approximation of centrality and distances in hyperbolic graphs
Victor Chepoi, Feodor F. Dragan, Michel Habib +2
We show that the eccentricities (and thus the centrality indices) of all vertices of a -hyperbolic graph can be computed in linear time with an additive one-sided erro…

Fast approximation and exact computation of negative curvature parameters of graphs
Jérémie Chalopin, Victor Chepoi, Feodor F. Dragan +3
In this paper, we study Gromov hyperbolicity and related parameters, that represent how close (locally) a metric space is to a tree from a metric point of view. The study of Gromov…
