Hi there, my goal is to make available the definition, example, etc from book (AMS) in book (koma-script). Now, I am not en expert and the fact that this has not been done, probably does have some reason which I, very well, might have missed. Anyways, what I did was to copy scrbook.layout to ~/.lyx/layouts and inset a
# \DeclareLaTeXClass[scrbook]{book (koma-script + AMS)} then I tried two things. First Input amsmaths.inc This did not work. Lyx: The document could not be converted into the document class scrbookAMS. Second I did: I am aware of http://www.troubleshooters.com/linux/lyx/index.htm#textclass_mod_tut and so I included Preamble \theoremstyle{plain} \newtheorem{thm}{Theorem}[section] EndPreamble but then I got the message that /theoremstyle{plain} is an undef. control sequence - which I agree to, but where do I get it from? I would appreciate any hints to enlighten my dull mind. Oliver Oliver Ruebenkoenig, <[EMAIL PROTECTED]> Phone: ++49 +761 203 7388
