To produce a bibliography, use the environment named
thebibliography. Input each reference as you would normally do in
LATEX [13]. Arrange the references in alphabetical
order by the last name of the first named author. The references at the
end of this sample file have been chosen to illustrate the coding of the
most common types of references. Use the abbreviations of names of
journals as given in annual indexes of Mathematical Reviews.
The sample references have been labeled with numbers, using
\bibitem{...}. To get letter labels use, for example,
\bibitem[C1]{...}.
References are set with hanging indentation. The widest label should be entered as the argument of the thebibliography environment, if you are not using BibTEX (which automatically determines the widest label). For example, a bibliography containing more than a hundred references would require three-digit number labels:
\begin{thebibliography}{000}
