Hi Jürgen, In response to your message on: 2008-06-01:
I tried using the layout file you posted and so far it works great. I'll report back if I experience any issues. If you can use redefinitions so that it uses 'thm' instead of 'theorem', which I think was an intentional change to make it work with the SIAM document class, then please let it just include the AMS files. I probably got rid of starred versions of theorems and other theorem types because if I remember correctly they weren't used by the SIAM document class. I can look into this more in two weeks (after qualifiers) if it would still be helpful at that point. In general, please feel free to make any changes you'd like to, I don't expect my permission to be sought. Andrew
