鞅在一类再保险风险模型及其破产概率中的应用
摘要
本文从保险公司的实际经营出发
引入一个新概念——再保险.对已有的风险模型进行推广
提出了一类带有干扰项且具有再保险收益的双复合Poisson模型
并利用鞅分析证明了其破产概率仍满足Lundberg不等式和一般公式.
Abstract
In this paper
the authors introduce a new concept-reinsurance.The exsisting model is extended to a reinsurance compound Poisson risk model with interference.The Lunderberg inequality and the common formula of the ruin probability are gotten in terms of some techniques from martingale theory.
