Cocompact CAT(0) spaces are almost geodesically complete
Pedro Ontaneda
We prove that, under certain mild conditions, every cocompact CAT(0) space is almost geodesically complete.
Cellular harmonic maps which are not diffeomorphisms
F. T. Farrell, P. Ontaneda
We give examples of harmonic cellular maps between negatively curved manifolds which are not diffeomorphisms but are homotopic to diffeomorphisms.
Continuous Symmetric Perturbations of Planar Power Law Forces
C. Azevedo, P. Ontaneda
We show the existence of periodic solutions for continuous symmetric perturbations of certain planar power law problems.
A caveat on the convergence of the Ricci flow for pinched negatively curved manifolds
F. T. Farrell, P. Ontaneda
We give examples of pinched negatively curved manifolds for which the Ricci flow does not converge smoothly.
Some Remarks on the Geodesic Completeness of Compact Nonpositively Curved Spaces
Pedro Ontaneda
We make some remarks on the existence of a geodesically complete core for any compact non-positively curved space.
A formula for the Whitehead group of a three-dimansional crystallographic group
A. Alves, P. Ontaneda
We give an explicit formula for Whitehead group of a three-dimensional crystallographic group in terms of the Whitehead groups of its virtually infinite cyclic subgroups.
