\section{Introduction}
When a Gaussian laser beam heats the interface separating two superimposed optically absorbing liquids, the inhomogeneous heating induces a local variation
of the interfacial tension which in turn generates tangential shear stresses and sets up hydrodynamic flows known as thermocapillary or Ma... | {

\section{Introduction and statements of the results}
This work is concerned with the dispersive property of the following class
of Schr\"odinger equations with singular homogeneous electromagnetic
potentials
\begin{equation} \label{prob}
iu_t=\left(-i\nabla+ \dfrac{{\mathbf{A}}\big(\frac{x}{|x|}\big)} {|x|}

\section{Introduction}
Since the $B_c$ meson is the lowest bound state of two different
heavy quarks with open flavor, it is stable against strong and
electromagnetic annihilation processes. The $B_c$ meson therefore
decays weakly. Furthermore, the $B_c$ meson has a sufficiently large
mass, thus each of the two ... | {

\section{Introduction}
Density functional theory (DFT) is perhaps one of the most successful
theories in Physics and in Chemistry of the last
half-century~\cite{PhysRev.136.B864,Parr1989,Dreizler90,Fiolhais2003}. It is currently
used to predict the structure and the properties of atoms, molecules,
and solids; it is a k... | {

\section{Introduction}
Recently, in \cite{Dallaporta/Vu:2011} and \cite{Dalla:2011} the Central Limit Theorem (CLT) for the eigenvalue counting function of {\it Wigner matrices},
that is the number of eigenvalues falling in an interval, was established. This {\it universality result} relies on fine asymptotics of the ... | {

\section{Introduction: Properties of Quiet Sun Internetwork Magnetic Fields}
Obtaining a clear picture of the solar magnetism and of the various
physical processes taking place in the solar atmosphere strongly
relies on the precise determination of the magnetic field vector. This
is very true for the tiny magnetic str... | {

\section{Introduction}
Recent numerical studies of gravitational collapse in isotropic coordinates, both in $4 +1$ dimensions (5D) \cite{Khlebnikov, C-E} and 4D \cite{C-E}, have provided numerical evidence that the negative of the total Lagrangian at late times of the collapse process approaches the Helmholtz free e... | {
