Actually, I have two problem with using the book(ams) class. First, I want to have a piece of abstract in my document just before the content list. But there is no option for this format in book(ams) class. Can I add abstract to the document manually, and how to do that?
Second, when ever I compile the lyx book file, all the child document are automatically opened. How can I avoid that? Thanks for your help in advance. Bests, Laser
