Global existence for semi-linear hyperbolic equations in a neighbourhood of future null infinity
J. Arturo Olvera-Santamaria
In this paper, we establish the global existence of a semi-linear class of hyperbolic equations in 3+1 dimensions, that satisfy the bounded weak null condition. We propose a confor…

Evolution and metric signature change of maximally symmetric spaces under the Ricci flow
R. Cartas-Fuentevilla, A. Herrera-Aguilar, J. A. Olvera-Santamaría
In this work we present solutions to the Ricci flow equations in arbitrary dimensions, particularizing for the and cases. We start by considering the case and note t…
