On Jump Measures of Optional Processes with Regulated Trajectories (1508.01973v1)
Published 9 Aug 2015 in math.PR
Abstract: Starting from an iterative and hence numerically easily implementable representation of the thin set of jumps of a c`{a}dl`{a}g adapted stochastic process $X$ (including a few applications to the integration with respect to the jump measure of $X$), we develop similar representation techniques to describe the set of jumps of optional processes with regulated trajectories and introduce their induced jump measures with a view towards the framework of enlarged filtration in financial mathematics.
