If I am not wrong, inserting the following line into your preamble should do the trick:
\newtheorem{theorem}{Theorem}[chapter]

Hi, I'm working on my thesis in lyx, it's a document of class book-AMS (so that I can use theorem, definition... formats)I want both theorems and definitions to be numbered within each chapter, not section (so, for example, the fifth definition in chapter 3 is defintion 3.5).Is there a way to do this at all? Thanks much Nathan
