Metastability of the two-dimensional Blume-Capel model with zero chemical potential and small magnetic field
C. Landim, P. Lemire
We consider the two-dimensional Blume-Capel model with zero chemical potential and small magnetic field evolving on a large but finite torus. We obtain sharp estimates for the tran…
On the variation of maximal operators of convolution type II
Emanuel Carneiro, Renan Finder, Mateus Sousa
In this paper we establish that several maximal operators of convolution type, associated to elliptic and parabolic equations, are variation-diminishing. Our study considers maxima…
Spontaneously stochastic solutions in one-dimensional inviscid systems
Alexei A. Mailybaev
In this paper, we study the inviscid limit of the Sabra shell model of turbulence, which is considered as a particular case of a viscous conservation law in one space dimension wit…
Complete connections on fiber bundles
Matias del Hoyo
Every smooth fiber bundle admits a complete (Ehresmann) connection. This result appears in several references, with a proof on which we have found a gap, that does not seem possibl…
A Proposal of a Damping Term for the Relativistic Euler Equations
Moritz Reintjes
We introduce a damping term for the special relativistic Euler equations in -D and show that the equations reduce to the non-relativistic damped Euler equations in the Newtonian…
Cech cohomology over
Jaret Flores, Matt Szczesny, Oliver Lorscheid
In this text, we generalize Cech cohomology to sheaves with values in blue -modules where is a blueprint with . If is an object of the underlying site,…
