Anyway, I get now only two numbers e.g. chnum.eqnum or sectnum.eqnum (according the \numberwithin arguments).In the previous version I had chnum.secnum.eqnum.
But this is what you get with this preamble: \numberwithin{section}{chapter} \numberwithin{equation}{section} \numberwithin{figure}{section} \numberwithin{table}{section} see attached file.
Do you know where I can get a real documentation for the amsbook class?
No, I don't. Numbering is a general LaTeX issue, so I refer to the book "The LaTeX Companion 2nd edition" Addison Weseley 2004. You can also google a bit for \numberwithin.
