An abstract should be written using the environment defined as in
this example file. The text describes briefly the use of the
\textbf{stochfin} class.
\end{abstract}
\section{Introduction}
This file gives a brief description of the class
\textbf{stochfin.cls}. This class is based on the standard
\textbf{article} class of the \LaTeX\ distribution. You have
available the standard commands and environments as is the
standard \textbf{article} class, with the changes that will be
described.
\section{Preamble}
As in the example file, the code starts with the instruction
\begin{verbatim}
\documentclass{scf2015}
\end{verbatim}
possibly with the usual optional arguments.
\noindent
There should be no \verb'\pagestyle' command.
\noindent
You should provide a \textit{title} and a \textit{running
title}. The instruction for this purpose is
\begin{verbatim}
\title{Running title}{Actual title}
\end{verbatim}
You are expected to give two arguments, even if they coincide.
Notice that the \textit{running title\/} is to be used in the
headers of the pages so it should not be long.
\noindent
For each author you should identify his/hers \textit{name}, an
\textit{abbreviated version of the name} and possibly include some
\textit{acknowledgments}. Also you should give the
\textit{address}. If they exist and you wish to make them available,
you may give the \textit{email} and the \textit{url}
addresses. For this purpose you should use the following
instructions:
\begin{verbatim}
\author{abbrev. name}{Full name\thanks{Any thanks}}
\address{Address of author}
\email{@somewhere.pt}
\url{http://www.somewhere.pt/$\sim$author1}
\end{verbatim}
Note that the \verb'\author' command expects two arguments, even
if they coincide.
\noindent
In case of several authors, you should use, in the order given,
the instructions concerning author 1, then author 2,and so on.
\noindent
Besides these instructions, include your command definitions.
Please note that if you use any non standard package you should
also send the file defining this package. If in doubt add
commented lines with a contact email or attach the file with your
submission.

\section{The document}
\subsection{Generating the title}
As expected, the body of the document should start with the
command \verb'\maketitle', which generates the title and the
identification of the authors.
\subsection{The abstract}
There is an environment to handle the layout of the abstract. It
goes, as expected, like this
\begin{verbatim}
\begin{abstract}
Abstract text.
\end{abstract}
\end{verbatim}
\subsection{Sectioning}
All the usual \LaTeX\ sectioning commands are available:
\verb'\section', \verb'\subsection', \verb'\subsubsection',
\verb'\paragraph', \verb'\subparagraph'.
\subsection{Environments}
All the usual \LaTeX\ environments are available: \verb'\center',
\verb'\description',\linebreak \verb'\enumerate', \verb'\figure',
\verb'\flushleft', \verb'\flushright', \verb'\itemize',
\verb'\list', \verb'\minipage', \verb'\picture',
\verb'\quotation', \verb'\quote', \verb'\tabbing', \verb'\table',
\verb'\tabular', \verb'\thebibliography'' \verb'\titlepage',
\verb'\verbatim', \verb'\verse'.
\medskip
\noindent
Although the \verb'\titlepage' is available you are kindly asked
to avoid it.
\medskip
\noindent
If including graphics or figures please attach the files. As it is
intended for the generation of pdf files, the use of png graphic
format files is preferred.
\subsection{Mathematical environments}
Almost all the usual \LaTeX\ mathematical environments are
available: \verb'\array', \verb'\eqnarray', \verb'\equation'. The
\verb'\theorem' is not defined. Instead the \textbf{stochfin}
class defines several theorem like environments ready to use:
\begin{center}
\begin{tabular}{ll|ll}\hline
Environment name & Heading & Environment name & Heading \\ \hline
thm & Theorem & prob & Problem \\
cor & Corollary & claim & Claim \\
lem & Lemma & fact & Fact \\
prop & Proposition & axiom & Axiom \\
defn & Definition & conj & Conjecture \\
exmp & Example & crit & Criterion \\
rem & Remark & prin & Principle \\
assum & Assumption & alg & Algorithm \\
hypo & Hypothesis & & \\ \hline
\end{tabular}
\end{center}
%\newtheorem{thm}{Theorem}[section]
%\newtheorem{cor}[thm]{Corollary}
%\newtheorem{lem}[thm]{Lemma}
%\newtheorem{claim}[thm]{Claim}
%\newtheorem{axiom}[thm]{Axiom}
%\newtheorem{conj}[thm]{Conjecture}
%\newtheorem{fact}[thm]{Fact}
%\newtheorem{hypo}[thm]{Hypothesis}
%\newtheorem{assum}[thm]{Assumption}
%\newtheorem{prop}[thm]{Proposition}
%\newtheorem{crit}[thm]{Criterion}
%\theoremstyle{plain}
%\newtheorem{defn}[thm]{Definition}
%\newtheorem{exmp}[thm]{Example}
%\newtheorem{rem}[thm]{Remark}
%\newtheorem{prob}[thm]{Problem}
%\newtheorem{prin}[thm]{Principle}
%\newtheorem{alg}{Algorithm}
The definitions of these environments take care of the numbering,
so please do not redefine the automatic numbering handled by
\LaTeX. Obviously the \verb'\label' and \verb'\ref' commands are
available.
\noindent
As an example, the code
\begin{verbatim}
\begin{thm}
This is supposed to be a theorem.
\end{thm}
\end{verbatim}
generates the text:
\begin{thm}
This is supposed to be a theorem
\end{thm}
Notice the this is the first theorem in section 3. If afterwards
we find the code
\begin{verbatim}
\begin{axiom}
This is supposed to be an axiom.
\end{axiom}
\end{verbatim}
we find the text:
\begin{axiom}
This is supposed to be an axiom.
\end{axiom}
We are still in section 3, but this is the second theorem like
structure used.
\medskip
\noindent
There is an environment to write \textit{proofs\/} of your
results. It goes like this:
\begin{verbatim}
\begin{proof}
Proof text.
\end{proof}
\end{verbatim}
and it generates the following text, with the black square flushed
right:\medskip
\begin{proof}
Proof text.
\end{proof}
\medskip
\noindent
Here follows an example of the use of a theorem like structure
with the respective proof.
\begin{prop}
This is supposed to be a proposition.
\end{prop}
\begin{proof}
And this should be the text that would prove whatever was stated,
ending with a black square flushed right.
\end{proof}
\noindent
If, for any reason, you want to use the black square that
identifies the end of proof you may use the command
\verb'\halmos'.
\section{References}
Please use the \verb'\thebibliography' environment with numbered
or named references. They should ordered by the last name of the
first author and be formatted as the examples that follow (here
using numbered references):
