基于经典系综模型,研究了Mg原子在低于重碰撞阈值激光功率密度下的非序列双电离(NSDI)。当少周期量级线性偏振激光的功率密度为3.0×10^(13) W·cm^(-2)时,末态关联电子动量分布中的电子对主要分布在第一、第二和第四象限,第一象限中的电子对呈现了明显的关联行为。分析了重碰撞和双电离之间的延迟时间,发现不同的延迟时间对应着不同的电离过程,延迟时间对电子出射过程具有显著影响;延迟时间小于半个周期的NSDI事件,双电子倾向于反方向出射,而延迟时间大于半个周期的,存在双电子同方向出射的可能。

该文研究了一个同时具有模型不确定性和违约风险的随机最优投资组合问题.假设在金融市场中包含三种资产:银行账户(无风险资产),股票资产及可违约债券.考虑一个保险公司把保费盈余投资在这三种资产上来最大化其效用函数.把模型的不确定性因素考虑进去,此时问题转化为一个在金融市场与保险公司之间的零和微分博弈问题.首先考虑了跳扩散风险模型而后又考虑了扩散逼近模型.在这两个模型中通过动态规划准则导出了Hamilton-JacobiBellman-Isaacs(HJBI)方程,从而求出了最优投资策略,并给出了验证定理.
