摘要
该文主要讨论了混合观测体系(hybrid observation scheme)下的谱负Lévy过程的Parisian破产问题.该文通过拉普拉斯变换法和测度变换法给出了破产时间和赤字的联合拉普拉斯变换.
In this paper,we consider Parisian ruin problem based on a hybrid observation scheme for a spectrally negative Lévy process.We obtain the joint Laplace transform of the time to ruin and the deficit at ruin time by using the method of Laplace transform and the change of measure technique.
