I need to write definition lemmas and theorems numbering according to chapter.
Like in chapter 1, definition number is 1.1, lemma is 1.2, theorem is 1.3. But by using commands \newtheorem{Defintion}{definition} I got definition 1, lemma 2, theorem 3.
Any one can please give me possible way to solve out this problem?
