Codimension two spacelike submanifolds into null hypersurfaces of generalized Robertson-Walker spacetimes
Luis J. Alias, Josue Melendez, Matias Navarro +1
We study codimension two spacelike submanifolds contained into a general class of null hypersurfaces in generalized Robertson-Walker spacetimes, refer to as nullcones. In particula…

On the sectional curvature along central configurations
Connor Jackman, Josué Meléndez
In this paper we characterize planar central configurations in terms of a sectional curvature value of the Jacobi-Maupertuis metric. This characterization works for the -body pr…
