Distributions of boundary functionals for processes with stationary independent increments are studied by many authors (see, e.g., [1-6]). If we restrict ourselves to the processes with a bounded variation and with the drift a [більше або дорівнює] 0 then from our results in [4-5] it is easy to deduce the relations defining distributions of functionals for a subordinator (process with positive and independent increments, see [3, Ch. III]).
