Abstract: We study null hypersurfaces approaching null infinity in asymptotically flat spacetimes within the Bondi–Sachs gauge. The null Raychaudhuri constraint is shown to asymptote to the Bondi mass-loss formula, interpreted as a stress tensor conservation law.… read more here.

Abstract: We consider a spatially extended mean-field model of a FitzHugh–Nagumo neural network, with a rescaled interaction kernel. Our main purpose is to prove that its asymptotic limit in the regime of st... read more here.
