In the template of a Springer journal there is no numbering procedure specified for the equations and there is only following lines as an example of an equation:

\begin{equation}
a^2+b^2=c^2
\end{equation}

This results in continuous numbering of equations. However, I've seen that in published papers of the same journal, the numbering restarts at each section.

Am I doing something wrong or it is the way it is supposed to be?

If numbering should restart at each section, how is that done?

  • Thanks to @luchonacho, [Here] (tex.stackexchange.com/questions/207532/…) is the answer to the second part of the question. However, I'd like to know if I should change the numbering or leave it be.

  • Is this not a matter of taste? If you are unsure, I would go for the one other papers in your field use. In any case, this is a very minor point, easy to correct in a future revision. So I would not bother very much with this.

  • In other papers numbering restarts too. So, I guess I'd just do that. Also, since I need that the number of sections to be included in equations number, this was very helpful.

  • If you want to publish in a journal, just use the journal class as it is or ask your editor. Things like numbering by section will usually be done by the editor/publisher. Jul 20 '17 at 12:55
  • @Schweinebacke -- not all publishers (i know you said "usually"). at ams, the author is usually considered to have decided on the appropriate numbering style, so it won't be changed unless there's a real error. Jul 20 '17 at 15:49

Answer for your question "If numbering should restart at each section, how is that done?" is

\usepackage{amsmath}
\numberwithin{equation}{section}
