Since I'm casting the final vote to close, a word of explanation: MathOverflow is intended for research-level questions, and your question, while natural, would belong better on math.stackexchange.com which is intended for a broader range of questions in mathematics. –  Yemon Choi Nov 14 '11 at 22:10
