Metric Graph Approximations of Geodesic Spaces

Facundo Memoli, Osman Berat Okutan, Qingsong Wang

We study the question of approximating a compact geodesic metric space by metric graphs satisfying a uniform upper bound on their first Betti number. We prove that, up to a suitabl…

Manifolds with positive orthogonal Ricci curvature

Lei Ni, Qingsong Wang, Fangyang Zheng

In this paper we study the class of compact Kähler manifolds with positive orthogonal Ricci curvature: $R i c^{⊥} > 0$ . First we illustrate examples of Kähler manifolds with $Ric^\pe…
