Isolated singularities of graphs in warped products and Monge-Ampère equations
José A. Gálvez, Asun Jiménez, Pablo Mira
We study graphs of positive extrinsic curvature with a non-removable isolated singularity in 3-dimensional warped product spaces, and describe their behavior at the singularity in…

Complete Surfaces with Ends of Non Positive Curvature
José A. Gálvez, Antonio Martínez, José L. Teruel
In this paper we extend Efimov's Theorem by proving that any complete surface in with Gauss curvature bounded above by a negative constant outside a compact set has…
