Xmacros as used with the \AmSTeX\ SIAM style file amstexsiam (version 2.0a).
XThe \AmSTeX\ SIAM style file, which
Xinputs and builds upon the amsppt style (version 2.1a or later)
Xof Michael Spivak, gives authors easy
Xaccess to most of the typographical constructions used in SIAM journals.
XIt does not address the issues of the table of contents

X\subhead 1. Introduction\endsubhead
XWe are concerned with numerical approximations to the so-called
Xporous-medium equation \cite{6},
X$$
X\alignedat2
X  &u_t=\phi(u)_{xx},&&\qquad x\in\Bbb R,\quad t>0,\quad\phi(u)=u^m,\quad m>1,
X\\
X  &u(x,0)=u_0(x),&&\qquad x\in\Bbb R.
X\endalignedat
X\tag 1.1
X$$
XWe assume that the initial data $u_0(x)$ has bounded support, that
X$0\leq u_0\leq M$, and that $\phi(u_0)_x\in\bvr$.
XIt is well known that a unique solution $u(x,t)$ of (1.1) exists,
Xand that $u$ satisfies
X$$
X  0\leq u\leq M\text{ and }\TV\phi(u(\,\cdot\,,t))_x\leq\TV\phi(u_0)_x.
X\tag 1.2
X$$
XIf the data has slightly more regularity, then this too is satisfied
Xby the solution. Specifically, if $m$ is no greater than two and
X$u_0$ is Lipschitz continuous, then $u(\,\cdot\,,t)$ is also Lipschitz;
Xif $m$ is greater than two and $(u_0^{m-1})_x\in\linfr$, then
X$(u(\,\cdot\,,t)^{m-1})_x\in\linfr$ 
X(see [3]). (This will follow from results presented here, also.)
XWe also use the fact that the solution $u$ is H\"older continuous in $t$.
X
X\subhead 2. $\linfr$ error bounds\endsubhead
XAfter a simple definition, we state a theorem
Xthat expresses the error of approximations $u^h$ in
Xterms of the weak truncation error $E$.
X\definition{Definition 2.1}\rm A {\it definition}
Xis the same as a theorem set in roman
Xtype.  In version 2 of the \AmSTeX\ style file for the SIAM journals,
Xdefinitions are set with their own command.
X\enddefinition
X\proclaim{Theorem 2.1}
XLet $\{u^h\}$ be a family of approximate solutions satisfying
Xthe following conditions for $0\leq t\leq T${\rm:}
X\roster
X\item For all $x\in\Bbb R$ and positive $t$, $0\leq u^h(x,t)\leq M${\rm;}
X\item Both $u$ and $u^h$ are H\"older--$\alpha$ in $x$
Xfor some $\alpha\in(0,1\wedge 1/(m-1))${\rm;} $u^h$ is right
Xcontinuous in $t${\rm;}
Xand $u^h$ is H\"older continuous in $t$ on
Xstrips $\Bbb R\times(t^n,t^{n+1})$, with the set $\{t^n\}$ having no
Xlimit points\/{\rm;} and
X\item There exists a positive function $\omega(h,\epsilon)$ such that\/{\rm:}
Xwhenever $\{w^\epsilon\}_{0<\epsilon\leq\epsilon_0}$ is a family of functions
Xin $\bold X$ for which
X{\roster
X\item"(a)" there is a sequence of positive numbers $\epsilon$ tending
Xto zero, such that for these  values of
X$\epsilon$, $\|w^\epsilon\|_\infty\leq 1/\epsilon$,
X\item"(b)" for all positive
X$\epsilon$, $\|w_x^\epsilon(\sdot,t)\|_\loner\leq 1/\epsilon^2$, and
X\item"(c)" for all $\epsilon>0$, 
X$$
X\sup\Sb
Xx\in\Bbb R\\0\leq t_1,t_2\leq T\endSb
X\dfrac{|w^\epsilon(x,t_2)-w^\epsilon(x,t_1)|}{|t_2-t_1|^p}\leq 1/\epsilon^2,
X$$
Xwhere $p$ is some number not exceeding $1$,
X\endroster}%
Xthen\footnote{This is an obvious ploy, but we need a footnote.}
X $|E (u^h,w^\epsilon,T)|\leq\omega(h,\epsilon).$
X\item
XThis is the fourth item in the outer roster.
X\endroster
XThen, there is a constant $C=C(m,M,T)$ such that
X$$\multline
X\|u-u^h\|_{\infty,\Bbb R\times[0,T]}\leq C\biggl[
X\sup \biggl |\int_\Bbb R(u_0(x)-u^h(x,0))  w(x,0) \,dx\biggr|\\
X+\omega(h,\epsilon)+\epsilon^\alpha\biggr],\endmultline
X\tag 2.1
X$$
Xwhere the supremum is taken over all $w\in\bold X$.
X\endproclaim
X
X\demo{Proof}
XWe assume first that $Q$ is decreasing and consider the following cases:
X\case{Case\/ {\rm1:}
X$b'\geq 1/2$} We have $P(1/8)\geq\delta>0$ where $\delta$
Xdepends only on $d$, for otherwise by (3.7) applied to $P$ and $p=\infty$,
X$P$ could not attain the value $1$ at $x=1$.  Similarly, for
X$m=(a'+b')/2$, $Q(m)\geq\delta'>0$ for some $\delta'$ depending only on $d$
Xsince otherwise $Q$ cannot attain the value $1$ at $x=a'$.  Hence, for
X$\delta''=\min(\delta,\delta')$, 
X$|A(y)|\geq|m-1/8|\geq b'/4\geq\frac18\max(b',1)$ for 
X$y\in[0,\delta'']$.  On the other hand,
X$|A(y)|\leq \max(b',1)$ for all $y\in[0,1]$, so (4.2) follows for
Xall $1\leq p\leq\infty$.
X\endcase
X\case{Case\/ {\rm2:}
X$b'\leq 1/2$} We have $P(3/4)\leq\delta<1$ with $\delta$
Xdepending only on $d$ for otherwise (3.7) applied to $1-P$ and $p=\infty$
Xwould show that $P$ could not attain the value $0$ at $x=0$.  It follows
Xthat $|A(y)|\geq 3/4-b'\geq 1/4$, $y\in[\delta,1]$, while $|A(y)|\leq 1$
Xfor all $y\in[0,1]$.  Hence (4.2) follows for
Xall $1\leq p\leq\infty$.
X\endcase
XWe consider now when $Q$ is increasing.  We can assume that $Q$ is not
Xa translate of $P$, i.e\., we do not have $P(x)=Q(x+\delta)$ for some $\delta$,
Xfor then (4.2) follows trivially.  In what follows, $C$ and $\delta$
Xdepend on $d$, and $C$ may depend on $p$.  We consider the following cases:
X\case{Case\/ {\rm3:} $a'\geq 1/4$ and $b'\leq 100$}
XFrom (3.7) for $P$
Xand $p=\infty$, it follows that $P(1/8)\geq\delta$ since otherwise $P$ cannot
Xattain the value $1$ at $x=1$.  Hence $|A(y)|\geq a'-1/8\geq1/8$ on
X$[0,\delta]$.  On the other hand $|A(y)|\leq b'$ for all $y\in[0,1]$ and hence
X(4.2) follows for all $1\leq p\leq\infty$.
X\endcase
XLet $z$ be in $\bold X$. Because $E(u,\sdot,\sdot)\equiv0$,
XEquation (1.5) implies that
X$$
X\int_\Bbb R\Delta uz|^T_0dx=\int_0^T\int_\Bbb R
X\Delta u(z_t+\phi[u,u^h]z_{xx})\,dx\,dt-
XE(u^h,z,t),
X\tag 2.2
X$$
Xwhere $\Delta u=u-u^h$ and 
X$$
X\phi[u,u^h]=\dfrac{\phi(u)-\phi(u^h)}{u-u^h}.
X$$
XExtend $\phi[u,u^h](\cdot,t)=\phi[u,u^h](\cdot,0)$ for negative $t$, and
X$\phi[u,u^h](\cdot,t)=\phi[u,u^h](\cdot,T)$
Xfor $t>T$.
XFix a point $x_0$ and a number $\epsilon>0$. Let $j_\epsilon$
Xbe a smooth function of $x$ with integral $1$ and support in 
X$[-\epsilon,\epsilon]$,
Xand let $J_\delta$ be a smooth function of
X$x$ and $t$ with integral $1$ and support in 
X$[-\delta,\delta]\times[-\delta,\delta]$; $\delta$ and $\epsilon$ are
Xpositive numbers to be specified later.
XWe choose $z=z^{\epsilon\delta}$ to satisfy
X$$
X\aligned
X  &z_t+(\delta+J_\delta*\phi[u,u^h])z_{xx}=0,\qquad x\in\Bbb R,\;0
X\leq t\leq T,\\
X  &z(x,T)=j_\epsilon(x-x_0).
X\endaligned
X\tag 2.3
X$$
XThe conclusion of the theorem now follows from (2.1) and the fact that
X$$
X|j_\epsilon*\Delta u(x_0,t)-\Delta u(x_0,t)|\leq C\epsilon^\alpha,
X$$
Xwhich follows from  Assumption 2.

X\centerline{\bf USING  THE \AmSTeX\ SIAM STYLE FILE}
X\medskip
X{\eightpt\centerline{BRADLEY J. LUCIER and DOUGLAS N. ARNOLD}}
X\bigskip
XThe \AmSTeX\ SIAM style file, amstexsiam.sty, is intended to help
Xauthors to produce a paper that is typographically acceptable for
Xpublication in a SIAM journal.  Beginning with version 2,
Xamstexsiam.sty inputs amsppt.sty and then makes modifications as
Xnecessary.  Version 2 of amstexsiam.sty works with version 2.1 of
X\AmSTeX\ and version 2.1a of amsppt.sty, and should work with latter
Xversions.  This brief guide assumes familiarity with \AmSTeX\ and
Xamsppt, as documented in {\it The Joy of \TeX\ } by Michael Spivak.
X
XMost of the points introduced below are illustrated in the nonsense
Xpaper {\it A sample paper, with a rather long title, to illustrate the 
X\AmSTeX\ SIAM style}.
X
X\heading{Publication information}  When the paper has been accepted,
X10 lines similar to these should be place immediately
Xafter the \v"documentsyle" line:
X\medskip
X\beginverbatim
X\accepted\SINUM

X\shortauthor{Bradley J. Lucier and Douglas N. Arnold}
X\shorttitle{A Sample Paper}                            
X\endverbatim
X\medskip\noindent
XThe \v"\accepted" macro should be followed by a control sequence taken
Xfrom the following table indicating the specific journal.
X\medskip
X\settabs\+\indent&Acronym\indent&Title&\cr
X\+& \v"\SINUM"&SIAM Journal on Numerical Analysis&\cr
X\+& \v"\SIREV"&SIAM Review&\cr

X\+& \v"\SICON"&SIAM Journal on Control and Optimization&\cr
X\+& \v"\SIDMA"&SIAM Journal on Discrete Mathematics&\cr
X\medskip\noindent
XThe next lines give information for the publication data printed at the
Xtop of the first page of the paper and for the running heads.  This
Xinformation consists of the first page number of the article, the last
Xpage number of the article, the journal name, the issue volume, the
Xissue number, the month of appearance, the year of appearance, the
Xplace of the paper in the issue, the head for even pages (the
Xauthor(s)'s name(s) shortened if necessary to fit on the headline), and
Xthe head for odd pages (the title shortened if necessary).  If the
X\v"\accepted" macro is not present, the publication information will be
Xignored except for \v"\shortauthor" and \v"\shorttitle", which may be
Xused for page headers.
X
X\heading{Top matter}  The {\it only}\/ constructions allowed between
X\v"\topmatter" and \v"\endtopmatter" are, in order, \v"\title" $\dots$ \v"\endtitle",
X\v"\author" $\dots$ \v"\endauthor", \v"\abstract" $\dots$ \v"\endabstract",
X\v"\keywords" $\dots$ \v"\endkeywords", and
X\v"\subjclass" $\dots$ \v"\endsubjclass".  (For special situations,
X\v"\pretitle", \v"\preauthor", \v"\preabstract", \v"\prekeywords",
X\v"\presubjclass", and \v"\prepaper" can also be defined; see {\it The
XJoy of \TeX\/}).
X
X\heading{Title} Use \v"\title" and \v"\endtitle".  Type the title in
Xall caps.  The title may have a footnote (at final publication time
Xthere will be a footnote indicating when the paper was received).  The
Xfootnote mark should be a bold asterisk obtained with
X\v"\footnote[\boldkey*]{Text of footnote.}".  All math should be typed using
X\v"\boldkey" and \v"\boldsymbol" to get bold italic Roman and Greek letters
Xand symbols; see {\it The Joy of \TeX\/}.
X
X\heading{Author} Use \v"\author" and \v"\endauthor".  Type the author's
Xname in all caps.  For multiple authors include the word ``and'' in
Xlowercase before the name of the last author.  For three or more
Xauthors follow each author's names except the last with a comma.  Give
Xthe affiliation of each author in a footnote attached to the author's
Xname (before the following comma, if any).  (Do {\it not} use the
X\v"\affil" or \v"\address" macros.) Statements acknowledging support
Xshould be contained in the same footnote.  The order of footnote
Xsymbols in these footnotes is dagger (\dag\thinspace =\thinspace
X\v"\dag"), double-dagger (\ddag\thinspace =\thinspace \v"\ddag"),
Xsection-marker (\S\thinspace = \thinspace\v"\S"), paragraph-marker
X(\P\thinspace = \thinspace\v"\P").
X
X\heading{Abstract} Use \v"\abstract" and \v"\endabstract".
X
X\heading{Keywords} Use \v"\keywords" and \v"\endkeywords".  Keywords are separated with commas but not followed by any punctuation.
X
X\heading{Subject classifications} Use \v"\subjclass" and
X\v"\endsubjclass".  Subject classifications are separated with commas
Xbut not followed by any punctuation.
X
X\heading{Footnotes} Use \v"\footnote".  Except for the topmatter, discussed
Xabove, use numbered footnotes.
X
X\heading{Headings} Use \v"\subheading" without ending punctuation.  The
Xargument usually begins with the section number followed by a period
Xand then the section name with only the first word capitalized.  Very
Xlong papers could use \v"\heading" and \v"\subheading".  If
X\v"\heading" is used, start heading name with a section mark
X(\S\thinspace =\thinspace\v"\S") and the section number followed by a
Xperiod and the section title with the first letter of each major word
Xcapitalized.  All math should be typed using
X\v"\boldkey" and \v"\boldsymbol" to get bold italic Roman and Greek letters
Xand symbols; see {\it The Joy of \TeX\/}.
X
X
X\heading{Equation numbers}  Use \v"\tag".
X
X\heading{Proclamations} Use \v"\proclaim" $\dots$ \v"\endproclaim"
Xfor theorems, lemmas, corollaries, claims, propositions, etc.  Use
X\v"\demo" $\dots$ \v"\enddemo" for proofs, \v"\remark" $\dots$ \v"\endremark"
Xfor remarks,
X\v"\definition" $\dots$ \v"\enddefinition" for definitions,
X\v"\example" $\dots$ \v"\endexample" for examples, and  \v"\case" $\dots$ \v"\endcase"
Xfor cases.  In each construction the
Xopening control sequence (\v"\proclaim", \v"\demo", $\dots$ ) takes
Xa single argument with no closing punctuation as in \v"\proclaim{Theorem 2.3}"
Xor \v"\demo{Proof}".  If remarks, examples, or cases are to be numbered,
Xyou must explicitly change to roman type for the number:
X\v"\remark{Remark \rom{3}}".
X
X\heading{Punctuation}  All vertical punctuation symbols, i.e.,~), (, :, ;,
X?, !, ],  and [, and numbers are to be set on roman type, even if in italic
Xtext (e.g.,~in proclaims or in the headings of demos, remarks, etc.).  One
Xcan do this with, for example, the \v"\rom" macro, as \v"{\it Assume that
X\rom{(1.1)} holds.}" or \v"{\it Fermat's Last Theorem is true \rom(this is new\rom).}", which yield {\it Assume that
X{\rm (1.1)} holds.} and {\it Fermat's Last Theorem is true {\rm(}this is new\/{\rm)}.}
X
X\heading{End-of-proof mark}The symbol signalling the end of a proof
Xis an open box, shown at the end of this paragraph.  It is obtained
Xwith \v"\qed".  Appropriate white space will be supplied
Xautomatically.\qed
X
X\heading{Lists and sublists}  Use \v"\roster" $\dots$ \v"\endroster".
XRosters use default labels of the form (1), (2), etc.  Subrosters are
Xpermitted.  Each subroster {\it must}\/ be enclosed in a separate pair
Xof braces.
X 
X\heading{References} Enclose the reference section with \v"\Refs"
X$\dots$ \v"\endRefs".  References are set just as described in {\it The
XJoy of \TeX.} Authors' names must be entered as first and possibly
Xmiddle initial, each followed by a period and a space, followed by the
Xlast name.  Only the first letter of the last name is capitalized. 
XUse \v"\by" before either \v"\ed" or \v"\eds".
X
X\heading{Figures and tables} There is only rudimentary support for
Xfigures and tables in the style file.  Use
X\v"\topinsert" $\dots$ \v"\endinsert" or
X\v"\midinsert" $\dots$ \v"\endinsert" to surround a figure, including the
Xcaption at the end as, for example, \v"\botcaption{Fig.~1} This is a
Xfigure caption.\endcaption".  Use \v"\topinsert" $\dots$ \v"\endinsert"
Xor \v"\midinsert" $\dots$ \v"\endinsert"to surround the table, including
Xthe caption at the start as, for example, \v"\topcaption{Table 1}This
Xline describes the table\endcaption".  
XPlace rules above and below column headings and at the
Xend of the table using \v"\hbox to \hsize{\hrulefill}".
X
X\heading{Table of contents} No special macros are provided to set
Xa table of contents.  You can try the macros described in {\it The Joy of
X\TeX\/}.  Otherwise, follow these
Xguidelines.  Switch to eight point type (\v"\eightpoint").
XCenter the word ``CONTENTS'' in caps.  Capitalize only the first word
Xof entries.  Runover lines align with the start of entries.
XPlace the section number flush left with one em to section title,
Xspaced dots from end of entry to page number, and two ems between the
Xdots and page number.  Leave 18--20 points of vertical space, baseline
Xto baseline, to the text above and below.
