摘要:
AbstractA class of diffusion processes following locally a vector field is constructed and the extended generator is computed for a subset of the domain of the generator. Using this theory, martingales for risk processes perturbed by diffusion are obtained. This leads to exponential bounds for the ruin probability in infinite as well as in finite time.
