| Abstract: | Inthis paper,a compound binomial risk model with diffusion and random investment returns under refunding process is discussed. The stable independent incrementality of the profit process and the relevant digital characteristics of the surplus process are obtained. The probability is calculated, and the expression of the final ruin probability and the Lundberg inequality are obtained. |
