[Tex/LaTex] LyX – Changing Section Numbering

Question

I'm really happy to try to get rid of MS Word once and for all.

So I start in the use of LateX.

I translate a philosophical book from English to French that contains a lot of mathematical equations. (For those interested, this is the first volume of Mario Bunge's Treatise on Basic Philosophy.)

I use LyX on Windows with the AMS Book document class.

As the screenshot shows, the section is numbered 1.1 and the subsection is numbered 1.1.1.

Is there a simple way to have the section numbered 1 and the subsection numbered 1.1 instead. In other words, I would like to remove the number associated with the chapter at the beginning of each section and subsection.

Maybe there is already a document class that numbers this way?

Thanks,

François

Answer 1

Follow the instructions here: https://tex.stackexchange.com/a/133689/120578

And add the commands:

\renewcommand*\thesection{\arabic{section}} 
\renewcommand*\thesubsection{\arabic{section}.\arabic{subsection}}

This will give you something like this:

Edit about no subsections in the TOC:

Add this line to under previous two:

\setcounter{tocdepth}{2}
