Streamer propagation in humid air
A. Malagón-Romero, A. Luque
We investigate the effect of humidity on the propagation of streamers in air. We present a minimal set of chemical reactions that takes into account the presence of water in a nont…
Renormalization and existence of the finite-time blow up solutions for a one-dimensional analogue of the Navier-Stokes equations
Denis Gaidashev, Alejandro Luque
The one-dimensional quasi-geostrophic equation is the one-dimensional Fourier-space analogue of the famous Navier-Stokes equations. In their work Li and Sinai have proposed a renor…
MHD equilibria with nonconstant pressure in nondegenerate toroidal domains
Alberto Enciso, Alejandro Luque, Daniel Peralta-Salas
We prove the existence of piecewise smooth MHD equilibria in three-dimensional toroidal domains of where the pressure is constant on the boundary but not in the inte…
On the emergence mechanism of carrot sprites
A. Malagón-Romero, J. Teunissen, H. C. Stenbaek-Nielsen +3
We investigate the launch of negative upward streamers from sprite glows. This phenomenon is readily observed in high-speed observations of sprites and underlies the classification…
Beltrami fields with hyperbolic periodic orbits enclosed by knotted invariant tori
Alberto Enciso, Alejandro Luque, Daniel Peralta-Salas
We prove that there exist Beltrami fields in Euclidean space, with sharp decay at infinity, which have a prescribed set of invariant tori (possibly knotted or linked) that enclose…
Effective bounds for the measure of rotations
Jordi-Lluís Figueras, Alex Haro, Alejandro Luque
A fundamental question in Dynamical Systems is to identify regions of phase/parameter space satisfying a given property (stability, linearization, etc). Given a family of analytic…
