A global stability result for incompressible magnetohydrodynamics
Livio Pizzocchero, Emanuele Tassi
We propose a result of global stability for the equations of homogeneous, incompressible magnetohydrodynamics (MHD) on a torus of any dimension , with positive v…
A note on "Algebraic approach to Casimir force between two -like potentials" (K. Ziemian, Ann. Henri Poincaré, Online First, 2021)
Davide Fermi, Livio Pizzocchero
We comment on the recent work [1], and on its relations with our papers [2,3] cited therein. In particular we show that, contrarily to what stated in [1], the Casimir energy densit…
Integrable scalar cosmologies with matter and curvature
Davide Fermi, Massimo Gengo, Livio Pizzocchero
We show that several integrable (i.e., exactly solvable) scalar cosmologies considered by Fré, Sagnotti and Sorin (Nuclear Physics \textbf{B 877}(3) (2013), 1028--1106) can be gene…
Gauge-invariant spherical linear perturbations of wormholes in Einstein gravity minimally coupled to a self-interacting phantom scalar field
Francesco Cremona, Livio Pizzocchero, Olivier Sarbach
Recently, there has been quite a lot of interest in static, spherical wormhole spacetimes and the question of their stability with respect to time-dependent perturbations. The cons…
On approximate solutions of the equations of incompressible magnetohydrodynamics
Livio Pizzocchero, Emanuele Tassi
Inspired by an approach proposed previously for the incompressible Navier-Stokes (NS) equations, we present a general framework for the a posteriori analysis of the equations of in…
On the necessity of phantom fields for solving the horizon problem in scalar cosmologies
Davide Fermi, Massimo Gengo, Livio Pizzocchero
We discuss the particle horizon problem in the framework of spatially homogeneous and isotropic scalar cosmologies. To this purpose we consider a Friedmann-Lemaitre-Robertson-Walke…
