\section{INTRODUCTION} A variety of models have been introduced in an attempt to explain quark confinement. The center vortices model \cite{Hoof79,Corn79} introduced in the late 1970's by 't Hooft is one of those attempts. A center vortex is a topological line-like (in D=3 dimensions) or surface-like (in D=4 dimensio...

\section{Introduction} The short-time motion of small particles fluctuating in a Newtonian fluid is strongly affected by fluid inertia, that is, the vorticity of the host fluid surrounding the dispersed particles. If a dispersed particle accelerates due to Brownian forces, it affects the motion of the host fluid in th...

\section{\bf Introduction} In a previous paper \cite{ITD2} we studied a scalar field theory model in which each field was associated with a distinct metric. For simplicity we assumed that spacetime was represented by a flat background and parametrised by coordinates $x^\mu$ such that the theory is invariant under the...

\section{Introduction} \label{Introduction} Trans-Neptunian Objects (TNOs) are thought to be among the least evolved relics of the solar system formation, residing in the outer parts of the solar system, where the influence of the Sun is less severe than in the inner parts of the solar system. Thus, these icy objects...

\section{Introduction.} One of the simplest sets that is widely studied by and most important to many mathematicians, in particular analysts and topologists, is Cantor's ternary set (also referred to as the middle third Cantor set), introduced by H.~Smith \cite{HS:1975} and by G.~Cantor \cite{GC:1883}. Cantor's terna...

\section{Introduction} An {\it overlap} is a word of the form $axaxa$, where $a$ is a single letter and $x$ is a (possibly empty) word. In 1980, Earl Fife \cite{Fife:1980} proved a theorem characterizing the infinite binary overlap-free words as encodings of paths in a finite automaton. Berstel \cite{Berstel:1994} l...

\section{The $U_L(3) \otimes U_R(3)$ symmetry.} The pattern of the lowest-lying states in the spectrum of strong interactions uncovers an approximate continuous symmetry of nature, the so-called {\it chiral symmetry}, which is spontaneously broken. The octet of pseudoscalar particles - $\pi$, $K$, and $\eta$ -, with ...

\section{Introduction} It is a standard topic in Banach space theory to investigate whether the convergence of functionals on a given Banach space in one topology implies the convergence in another finer one. In this paper we study the following instance of this problem. Let $\mathcal{A}$ be a $\sigma$-complete Boolea...

\section{Introduction} \label{se:introduction} In the past few years a number of papers have discussed the inclusion of weak boson finite-width effects in the theoretical predictions for $e^+e^-$ processes. A careful treatment is required since these effects are intimately related to the gauge invariance of the theory...

\section{Introduction} For nearly three decades, the analysis on metric measure spaces has been under active study, e.g., \cite{BB11,BBS,BBS03,H03,HP,H,HK,HKST}. Given a metric measure space $(Z, d_Z, \nu_Z)$, many function spaces defined on this space have been well established, e.g., Sobolev spaces, Besov spaces and...

\section{Introduction} In this paper, all graphs are finite and simple, which means no parallel edges and no loops at their vertices. A proper $k$-coloring of a simple graph $G$ is an assignment (or a special case of labeling) of $k$ colors to the vertices of $G$ so that no two adjacent vertices share the same color....
