摘要 利用ITO公式和级数展开建立了最优投资决策问题的期望效益的一个数学表示,并由此给出了Merton关于最优投资决策问题的一个重要结果的简化证明,同时还给出了一个判断投资决策问题的最优停止时刻的充分条件. A mathematical formula for the expected utility of an optimal portfolio problem is established with the employment of (ITO) formula and Lie series. An analysis is made of some applications of the mathematical formula , including a simplified verification of one of Merton's conclusions. The mathematical formula is also used to deal with a local time-optimal problem.
