关于常利率风险模型在破产前后余额的分布

摘要

In this paper,applying Laplace transform we give the formulae of the distributions of the surplus of constant interest force risk model prior to and at ruin,which are expressed by some ruin probability,and an analytical expression for ruin probability.We also briefly consider the joint density of the surplus proior to and at ruin.%本文对常利率风险模型运用拉普拉斯变换给出了破产前后余额通过破产概率函数表示的有限公式,以及破产概率的分析表达式,另外对于破产前后余额分布的密度与破产前余额密度之间关系简要说明.
