Page Layout ⇒ Chapter mark in section title

[zdavies]

I would like to change the the numeration on section titles: at the moment my section titles look like this:
SectionNumber. SectionTitle
E.g. 1. Introduction.

I want to change them to look like this:
ChapterNumber.SectionNumber. SectionTitle
E.g. 1.1. Introduction.

Is there a simple way to so this?

This can only work when changing from the article class to a chapter based class like book or report. You may take a look at the memoir class or those from the KOMA Script bundle.


Best regards and welcome to the board

I am already using amsbook.cls which is a chapter class. However the section headings do not include the chaptermark in the section title.

I am already using amsbook.cls which is a chapter class.

This very important information would have been useful right at the beginning. Add a line to your preamble.

Code: Select all

\numberwithin{section}{chapter}

This command is provided by the amsmath package which is automatically loaded by the class.
