报告摘要: In this talk we find the Laplace transforms of weighted occupation times for a spectrally negative Levy surplus process to spend below its running maximum up to the first exit times. The results are expressed in terms of generalized scale functions for the spectrally negative Levy surplus process. For step weight functions, the Laplace transforms can be further expressed in term of scale functions.
