Fundamental groups of aspherical manifolds that collapse
Sergio Zamora
We show that if a sequence of closed aspherical -dimensional Riemannian manifolds with Ricci curvature uniformly bounded below and diameter uniformly bounded above collaps…

Tori Can't Collapse to an Interval
Sergio Zamora
Here we prove that under a lower sectional curvature bound, a sequence of Riemannian manifolds diffeomorphic to the standard -dimensional torus cannot converge in the Gromov--Ha…

Gözde Sert, Sergio Zamora
We give a short proof of a result obtained by Mohammad Ghomi concerning existence of nets of a convex polyhedron after a suitable linear transformation.
