You can make use of mathtools' multlined environment: \documentclass{article} \usepackage{amsmath,mathtools} \begin{document} \[ \begin{split} x &= a + a \\ &= b + b + b + b \\ &= \!\begin{multlined}[t] c + c + c + c + c + c + c + c + c + c + c + c \\ + c + c + c + c + c + c + c + c + c + c \end{multlined} ...

The standard and easiest method is to just add a line to the split and move right by, say, one quad. This is the method I'd prefer, not bothering about alignment. Alternatively, use multlined from mathtools: \documentclass{article} \usepackage{amsmath,mathtools} \begin{document} \[ \begin{split} x &= a + a \\ &= b + b + b + b \\ &= c + c + ...

That is the class default behavior. svjour3.cls includes \PassOptionsToPackage{fleqn}{amsmath}} So that the default \documentclass[twocolumn, final]{svjour3} \usepackage{amssymb} \usepackage{mathtools} \usepackage{lipsum} % just for the demo \DeclareMathOperator{\Norm}{Norm} \begin{document} \lipsum[1-5] % Just for the demo ...

svjour3.cls defines fleqn as a class option, but also passes that option to amsmath if its loaded: \DeclareOption{fleqn}{\input{fleqn.clo}\AtBeginDocument{\mathindent\z@}% \AtBeginDocument{\@ifpackageloaded{amsmath}{\@mathmargin\z@}{}}% \PassOptionsToPackage{fleqn}{amsmath}} And, under the twocolumn document class option, it necessarily also uses ...

Just replace \frac{b*a^x_2}{b*a^x_1} with \frac{b*a^{x_2}}{b*a^{x_1}}.

Do you mind something like this: \documentclass{article} \usepackage{mathtools,array} % for show equation only \usepackage[active,tightpage]{preview} \PreviewEnvironment{equation} \setlength\PreviewBorder{1em} \begin{document} \left[\begin{tabular}{@{}>{$}c<{$}@{}} \dfrac{\left(\vec{A} - ...

You can do it with delarray, but I think it's much better the second way I propose. \documentclass{article} \usepackage{amsmath} \usepackage{delarray} \begin{document} Here's a fraction with very large numerator \begin{equation*} \begin{array}\lbrack{@{}c@{}}\rbrack \dfrac{\left(\vec{A} - \dfrac{b}{c} \vec{D} \right)^2}{E^2} \end{array}^{1/2} ...

You could use a stack, for example. If the line heights were uniform, this would work: \documentclass{article} \usepackage{amsmath,stackengine} \stackMath \begin{document} \[ \begin{split} x &= a + a \\ &= b + b + b + b \\ &= \stackengine{\baselineskip}{c + c + c + c + c + c + c + c + c + c + c + c} {{}+ c + c + c + c + c + c + c + c + ...

When I compile the OP's snippet, I do not get the left/right offset that is shown in his image. The OP will need to provide a complete working example to demonstrate the problem. When I wrap the OP's provided code in a document with amsmath, I get this image: which is centered, but of uneven width. One thing that can be done is to redefine the length ...

Well, you can change \@eqnnum but whether this is what you want is impossible to say without more details about your class code and your desired results. \documentclass{article} \usepackage{xcolor,etoolbox} \makeatletter \patchcmd{\@eqnnum}{\normalcolor}{\color{magenta}}{\typeout{eqnnum patch: OK!}}{\typeout{eqnnum patch: Oh, dear!}} \begin{document} ...

I use the pdfocr program with tesseract when I want to ocr my pdf's on linux I use the ppa:gezakovacs/pdfocr repository for pdfocr and sudo apt-get update sudo apt-get install pdfocr sudo apt-get install tesseract-ocr sudo apt-get install tesseract-ocr-eng The command to convert is pdfocr -i input.pdf -o output.pdf In addition, prior to ...
