This paper proposes a novel method for co-ranking authors and their publications using several networks: the social network… (More)

Let M be a PL-manifold of nonnegative curvature that is homeomorphic to a product of two spheres, S × S. We prove that M is a direct metric product of two spheres endowed with some polyhedral metrics. In other words, M is a direct metric product of the surfaces of two convex polyhedra in R. The background of the question is the following. In the Riemannian… (More)
