A stationary spacetime $(V^{(4)},g^{(4)})$ is a 4-manifold $V^{(4)}$ equipped with a smooth Lorentzian metric $g^{(4)}$ of signature $(-,+,+,+)$, which in addition admits a time-like Killing vector field. A trivial example is the Minkowski space $(\mathbb{R}^{4}, g_{\text{Min}})$, where

\label{sec:introduction}
One consequence of the principle of relativity, which from a purely
mathematical standpoint can be considered an instance of Klein's
Erlanger Programme, is that the geometry of the universe is dictated
by its Lie group of automorphisms. As in Klein's programme, by

\section{Introduction}
Networks are the backbone of modern society.
Social networks, the internet, and energy networks, are examples of some of the critical networks that we rely on their operation in our daily lives.
As such, the control, security, and management of these and other types of networks are of paramount... | {

\section{Introduction}
In the theory of constant mean curvature $H$ surfaces ($H$-surfaces in the sequel), the existence of compact embedded examples in different three-manifolds has been an appealing problem whose origins probably date back to the mid twentieth century and the Alexandrov problem. Although simply conn... | {

Many practical tasks in machine learning rely on computing a Wasserstein distance between probability measures or between their sample points~\citep{arjovsky2017wasserstein,thorpe2017transportation,ye2017fast,srivastava2015wasp}. However, the high computational co... | {

\section{Introduction}
Interdependent networked systems are particularly vulnerable to damage, as damaged sites in one sub-system cause failures in another, which may in turn propagate damage back to the first \cite{buldyrev2010catastrophic}. Under sufficient damage, avalanches of propagating failures may eventually l... | {

\section{Introduction}
We recently reported the results of a low-resolution ($\theta =
8\arcsec$ FWHM) S-band ($2 < \nu < 4$~GHz) image
made with the
NRAO\footnote{The National Radio Astronomy Observatory is a facility

\section{Introduction}
The planar Magnetohydrodynamics (MHD) system with constant longitudinal magnetic field is governed by the following equations:
\begin{equation}\label{e1}
\left\{\begin{split}
&\rho_t+(\rho u)_x=0,\\
&(\rho u)_t+\left(\rho u^2+p+\frac12 |\mathbf{b}|^2\right)_x

\section{Introduction}
The Gamma Beam Source~\cite{Bacc2013} (GBS) machine is an advanced source of up to $\approx$\SI{20}{MeV} Gamma rays based on Compton back-scattering, i.e. collision of an intense high power laser beam and a high brightness electron beam with maximum kinetic energy of about \SI{720}{MeV}.
