Query: Kendall random walk, Williamson transform and the corresponding
  Wiener-Hopf factorization   The paper gives some properties of hitting times and an analogue of the
Wiener-Hopf factorization for the Kendall random walk. We show also that the
Williamson transform is the best tool for problems connected with the Kendall
generalized convolution.
