Journal of Mathematical Physics, 2016 We construct a family of constant curvature metrics on the Moyal plane and compute the Gauss-Bonnet term for each of them. They arise from the conformal rescaling of the metric in the orthonormal frame approach.

La dimensión transescalar del hábitat humano.
Inmaterial, 2021 El hogar y la ciudad son dos dimensiones escalares diferentes del hábitat humano que están fuertemente interconectadas. El confinamiento pandémico no sólo lo ha puesto de manifiesto, sino que en muchos casos ha llevado las situaciones espaciales al ...

MINIMAL IMMERSIONS OF SPHERES INTO SPHERES [PDF]
Proceedings of the National Academy of Sciences, 1969 In this paper we announce a qualitative description of an important class of closed n -dimensional submanifolds of the m -dimensional sphere, namely, those which locally minimize the n -area in the same way that geodesics minimize the arc length and are themselves ...

Minimal 2-spheres in 3-spheres [PDF]
Duke Mathematical Journal, 2019 We prove that any manifold diffeomorphic to $S^3$ and endowed with a generic metric contains at least two embedded minimal two-spheres. The existence of at least one minimal two-sphere was obtained by Simon-Smith in 1983. Our approach combines ideas from min-max theory and mean curvature flow.
