Query: Generalized L/'evy Stochastic Areas and Selfdecomposability   We show that a conditional characteristic function of generalized L\'evy
stochastic areas can be viewed as a product a selfdecomposable distribution
(i.e., L\'evy class L distribution) and its background driving characteristic
function. This provides a stochastic interpretation for a ratio of some Bessel
functions as well as examples of characteristic functions from van Dantzig
class.
