There are many question and answers already on the subject, but I have not found any suitable one for my request, so I hope you can help me.
I have two quite big systems of equations, one is the log-linearization of the other. I would like numbering of the form:
\section{First section}
... (1a)
... (2a)
... (3a)
\section{Second section}
... (1b)
... (2b)
... (3b)
where the ellipses stand for equations. As one equation exactly relates to the other, I find this a much better structure in my thesis than simply writing equations (1) to (6). Also, I am not too fixated on the exact notation, so if someone has a better way of doing this, I am eager to here it.
Here is a MWE:
\documentclass[a4paper,12pt]{report}
\usepackage{amsmath,amsfonts,amssymb}
\usepackage{textcomp,mathrsfs,xcolor,float,fancyhdr}
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc} \pagenumbering{arabic}
\begin{document}
\chapter{Equilibrium}
\section{Deflated Equilibrium}
\begin{equation}
a=b
\end{equation}
\begin{align}
b=c \\
c=d
\end{align}
\section{Log-Lin Equilibrium}
\begin{equation}
a=b
\end{equation}
\begin{align}
b=c \\
c=d
\end{align}
\end{document}}
\renewcommand{\theequation}{\arabic{equation}\alph{section}}
for example? But does allow for 26 sections only, I don't know if this will be enough then ;-)equation
only? Noalign
environment with more than one line such that those are numbered as well? And how do you settle the connection between, say1a
and1b
-- is this just the order of equations?
