# Style files

There are two journal style files for Mathematica Scandinavica

`mathscan.cls`: the LaTeX class file`mscplain.bst`: the BibTeX style file

The class file is based on the `amsart.cls` for LaTeX, but documents written with the standard `article.cls` can also be adapted to the journal style. The following points describe what to do.

- Download the
`mathscan.cls`file from the above link and put it in your working directory. - Write (or modify) the first line of the preamble to be

Do not load the`\documentclass{mathscan}`

`geometry`package or change dimensions such as the`\textwidth`

. The class file loads most of the standard`amsmath`related packages, so you do not need to load these explicitly. - Your
`\newtheorem`

-commands should be plain and without font commands. Use the switch`\theoremstyle{definition}`

to get the body text to be roman for Definitions and Remarks etc.:`\newtheorem{thm}{Theorem}[section] \newtheorem{pro}[thm]{Proposition} \newtheorem{cor}[thm]{Corollary} \newtheorem{lem}[thm]{Lemma} \theoremstyle{definition} \newtheorem{rem}[thm]{Remark} \newtheorem{defn}[thm]{Definition} \newtheorem{exam}[thm]{Example} \numberwithin{equation}{section}`

- Use
`\mathbb`

for the symbols for the reals, integers, etc., preferably via definitions like

Do not use the obsolete command`\newcommand{\bR}{\mathbb{R}} \newcommand{\bZ}{\mathbb{Z}}`

`\Bbb`

. Similarly, use`\emph`

and`\textbf`

instead of the obeselete commands`\it`

and`\bf`

. Do not change the meaning of standard LaTeX commands. - The
`proof`

environment is already defined in`mathscan.cls`. Mathematica Scandinavica does*not*use an end of proof symbol, instead make sure your proofs end with some suitable phrase:as claimed

, orcompleting the proof

. - Footnotes should be avoided throughout. Acknowledgements may be placed at the end of the main text in
`\begin{acknowledgements}...\end{acknowledgements}`

- Figures should be allowed to float. Image files should be in a vector graphic format such as
`.eps`. Tables, if needed, are best formatted using the`booktabs.sty`package. - References should be prepared either using the
`\begin{thebibiliography}...\end{thebibliography}`

or via BibTeX using the`mscplain.bst`style file provided above. Please do not use`biblatex.sty`or`amsrefs.sty`. - Do not worry about line spacing irregularities in the paper version you send to mscand. These will be taken care of by the typesetter! Vertical skips other than those that the Latex-environments produces automatically should be kept to a minimum; please be conservative. If you use such (extra) vertical skips between paragraphs, they should be justified by a suitable change of content (as if you are suppressing a subsection-title). Prefer
`\smallbreak`

to`\smallskip`

. - For documents of
`article.cls`: if you modify from a document written with the standard LaTeX article class, some words of warning are in order.- Do not call the package
`amsmath.sty`(it is done already). - Do not call packages like
`theorem.sty`or other theorem packages (`amsthm.sty`is already loaded). - The abstract should be contained in an environment
`\begin{abstract}...\end{abstract}`

and this should come*before*`\maketitle`

. - All of the commands
`\title`

,`\author`

,`\address`

,... should be in the text (not in the preamble), i.e. after`\begin{document}`

, but before`\maketitle`

. - Equations should be referenced with
`\eqref`

rather than`\ref`

.

- Do not call the package

Here is a small skeleton document containing a typical preamble and title material:

\section{Introduction}
\label{Intro}
Main text starts here.
We cite the paper~\cite{Knudsen76}.
\section{Previous results}
Consider
\begin{equation}
\label{eq:x}
x = yz.
\end{equation}
\begin{thm}
\label{thm:y}
If $z \ne 0$, then $y = x/z$.
\end{thm}
\begin{proof}
This follows from equation~\eqref{eq:x}.
\end{proof}
Theorem~\ref{thm:y} is not new.
