Periodic Delaunay cylinders with constant anisotropic nonlocal mean curvature
Francesc Alcover, Renzo Bruera
In this article we prove existence and symmetry properties of periodic surfaces of revolution with constant anisotropic nonlocal mean curvature, generalizing a classical result of…

Nonlocal BV and nonlocal Sobolev spaces induced by nonfractional weight functions
Francesc Alcover, Joan Duran, Ramon Oliver-Bonafoux +1
In this paper, we expand upon the theory of the space of functions with nonlocal weighted bounded variation, first introduced by Kindermann et.al. in 2005 and later generalized by…

Super-Resolution of Sentinel-2 Images Using a Geometry-Guided Back-Projection Network with Self-Attention
Ivan Pereira-Sánchez, Daniel Torres, Francesc Alcover +4
The Sentinel-2 mission provides multispectral imagery with 13 bands at resolutions of 10m, 20m, and 60m. In particular, the 10m bands offer fine structural detail, while the 20m ba…
