Intertwining certain fractional derivatives
Abstract
We obtain an intertwining relation between some Riemann-Liouville operators of order a in (1,2) connecting through a certain multiplicative identity in law the one-dimensional marginals of reflected completely asymmetric a-stable L\'evy processes. An alternative approach based on recurrent extensions of positive self-similar Markov processes and exponential functionals of L\'evy processes is also discussed.
