Abstract: | Several two-boundary problems are solved for a special Lévy process: the Poisson process with an exponential component. The
jumps of this process are controlled by a homogeneous Poisson process, the positive jump size distribution is arbitrary, while
the distribution of the negative jumps is exponential. Closed form expressions are obtained for the integral transforms of
the joint distribution of the first exit time from an interval and the value of the overshoot through boundaries at the first
exit time. Also the joint distribution of the first entry time into the interval and the value of the process at this time
instant are determined in terms of integral transforms. |
