Flying randomly in Rd with Dirichlet displacements

Random flights in Rd,d≥2, with Dirichlet-distributed displacements and uniformly distributed orientation are analyzed. The explicit characteristic functions of the position X¯d(t),t>0, when the number of changes of direction is fixed are obtained. The probability distributions are derived by inverting the characteristic functions for all dimensions d of Rd and many properties of the probabilistic structure of X¯d(t),t>0 are examined.
