摘要: 本文考虑了带息力的Erlang(2)风险模型,利用Sundt和Teugels(1995),Yang和Zhang(2001a,2001b和2001c)文中的技巧,得到了生存概率所满足的积分方程和指数型的积分方程,然后研究了生存概率的Laplace-Stieltjes变换所满足的二阶微分方程。

Abstract: In this paper, we consider an Erlang(2) risk model with a constant interest force for an insurance portfolio. By using the techniques of Sundt & Teugels (1995) and Yang & Zhang (2001a, 2001b and 2001c), the integral equation and exponential integral equation satisfied by survival probability have been obtained. Then we have investigated the two-order differential equation satisfied by the Laplace-Stieltjes transform of survival probability. -
