# Cuparticle.cls

## Usage

The class should be loaded with the command:

 \documentclass[<options>]{cuparticle}

where the options can be the following:

preprint
default option which format the document for submission to CUP journals.
nopreprintline
Suppresses the preprint line in the title page.
review
similar to the preprint option, but increases the baselineskip to facilitate an easier review process.
fms
formats the article for the submission to Forum Maths Sigma' journal.
fmpi
formats the article for the submission to Forum Maths Pi' journal.
footmarks
print footnote marks for title and author footnotes. The default style is no footnote marks.
authoryear
author–year citation style of natbib.sty. If you want to add extra options of natbib.sty, you may use the options as comma delimited strings as arguments to the \biboptions command. An example would be:

 \biboptions{longnamesfirst,angle,semicolon}
number
numbered citation style which is the default. Extra options can be loaded with \biboptions command.
sort&compress
sorts and compresses the numbered citations. For example, citation [1,2,3] will become [1-3].
longtitle
if front matter is unusually long, use this option to split the title page across pages with the correct placement of title and author footnotes in the first page.
times
loads txfonts.sty, if available in the system to use Times and compatible math fonts.
• All options of article.cls can be used with this document class.
• The default options loaded are a5paper, 10pt, oneside, onecolumn and preprint.

## Floats

Figures may be included using the command, \includegraphics in combination with or without its several options to further control graphics. \includegraphics is provided by graphic[s,x].sty which is part of any standard LaTeX distribution. graphicx.sty is loaded by default. LaTeX accepts figures in the postscript format while pdfLaTeX accepts *.pdf, *.mps (metapost), *.jpg and *.png formats. pdfLaTeX does not accept graphic files in the postscript (EPS) format.

The table environment is handy for marking up tabular material. If users want to use multirow.sty, array.sty, etc., to fine control/enhance the tables, they are welcome to load any package of their choice and cuparticle.cls will work in combination with all loaded packages.

## Theorem and theorem-like environments

cuparticle.cls provides a few shortcuts to format theorems and theorem-like environments with ease. In all commands the options that are used with the \newtheorem command will work exactly in the same manner.

\newtheorem{theorem}{Theorem}
\newdefinition{definition}{Definition}
\newproof{proof}{Proof}

The \newtheorem command formats a theorem, lemma etc. in LaTeX's default style with italicized font, bold font for theorem heading and theorem number at the right hand side of the theorem heading. It also optionally accepts an argument which will be printed as an extra heading in parentheses. The following text will show you how some text enclosed in \begin{theorem} . . . \end{theorem} will look like.

The \newdefinition command is the same in all respects as its \newtheorem counterpart except that the font shape is roman instead of italic. Both \newdefinition and \newtheorem commands automatically define counters for the environments defined. See the output of \begin{definition} . . . \end{definition} which is given below.

The \newproof command defines proof environments with upright font shape. No counters are defined. See the output of \begin{proof} . . . \end{proof}.

Users can also make use of amsthm.sty which will override all the default definitions described above.

## Enumerated and Itemized Lists

cuparticle.cls provides extended list processing macros which makes the usage a bit more user friendly than the default LaTeX list macros. With an optional argument to the \begin{enumerate} command, you can change the list counter type and its attributes.

\begin{enumerate}[1.]
\item The enumerate environment starts with an optional argument 1.', so that the item counter will be suffixed  by a period.
\item If you provide a closing parenthesis to the number in the  optional argument, the output will have closing parentheses for all the item counters.
\item You can use (a)' for alphabetical counter and '(i)' for  roman counter.
\begin{enumerate}[a)]
\item Another level of list with alphabetical counter.
\item One more item before we start another.
\begin{enumerate}[(i)]
\item This item has roman numeral counter.
\item Another one before we close the third level.
\end{enumerate}
\item Third item in second level.
\end{enumerate}
\item All list items conclude with this step.
\end{enumerate}

The typeset copy of the above source code is given below:

Furthermore, the enhanced list environment allows one to prefix a string-like step' to all the item numbers. Take a look at the example below:

\begin{enumerate}[Step 1.]
\item This is the first step of the example list.
\item Obviously this is the second step.
\item The final step to wind up this example.
\end{enumerate}

The typeset copy of the above source code is given below:

## Cross-references

In electronic publications, articles may be internally hyperlinked. Hyperlinks are generated from proper cross-references in the article. For example, the words Fig. 1 will never be more than a simple text, whereas the proper cross-reference \ref{tiger} may be turned into a hyperlink to the figure itself: Fig. 1. In the same way, the words Ref. [1] will fail to turn into a hyperlink; the proper cross-reference is \cite{Knuth96}. Cross-referencing is possible in LaTeX for sections, subsections, formulae, figures, tables, and literature references.

## Mathematical symbols and formulae

Many physical/mathematical science authors require more mathematical symbols than the few that are provided in standard LaTeX. A useful package for additional symbols is the amssymb package, developed by the American Mathematical Society. This package includes such oft-used symbols as \lesssim, \gtrsim or \hbar. Note that your TeX system should have the msam and msbm fonts installed. If you need only a few symbols, such as \Box, you might try the package latexsym.

Another point which would require the authors' attention is the breaking up of long equations. When you use elsarticle.cls for formatting your submissions in the preprint mode, the document is formatted in single column style with a text width of 384pt or 5.3in. When this document is formatted for final print and if the journal happens to be a double column journal, the text width will be reduced to 224pt for 3+ double column and 5+ journals respectively. All the nifty fine-tuning in equation breaking done by the author goes to waste in such cases. Therefore, authors are requested to check this problem by typesetting their submissions in the final format as well just to see if their equations are broken at the appropriate places, by changing appropriate options in the document class loading command, which is explained in the section Usage. This allows authors to fix any equation breaking problem before submission for publication. cuparticle.cls supports formatting the author submission in different types of final format. This is further discussed in the section Final print.

## Bibliography

In the LaTeX literature, references are listed in the thebibliography environment. Each reference is a \bibitem and each \bibitem is identified by a label, by which it can be cited in the text: \bibitem[Elson et al.(1996)]{ESG96} is cited as \citet{ESG96}. In connection with cross-referencing and possible future hyperlinking it is not a good idea to collect more than one literature item in one \bibitem. The so-called Harvard or author–year style of referencing is enabled by the LaTeX package natbib. With this package the literature can be cited as follows:

• Parenthetical: \citep{WB96} produces (Wettig & Brown, 1996).
• Textual: \citet{ESG96} produces Elson et al. (1996).
• An affix and part of a reference: \citep[e.g.][Ch. 2]{Gea97} produces (e.g. Governato et al., 1997, Ch. 2).

In the numbered scheme of citation, \cite{<label>} is used, since \citep or \citet has no relevance in the numbered scheme. natbib package is loaded by cuparticle.cls with numbers as default options. You can change this to the author–year or harvard scheme by adding option authoryear in the class loading command. If you want to use more options of the natbib package, you can do so with the \biboptions command, which is described in the section Usage. For details of various options of the natbib package, please take a look at the natbib documentation, which is part of any standard LaTeX installation.
