RIGHT INVERSES OF LEVY PROCESSES: THE EXCURSION MEASURE IN THE GENERAL CASE

While these known formulas relate to excursions away from a point starting negative continuously, and excursions started by a jump, the present description is in terms of excursions away from the supremum continued up to a return time. …”
