Query: On intertwining relations between Ehrenfest, Yule and Ornstein-Uhlenbeck
  processes   Markovian intertwining relations between two Markov semigroups are related to
the partial inclusion of the spectra of their generators, at least for finite
ergodic processes. We check the limitations of this observation by
investigating the Markov intertwining relations between the Ehrenfest, Yule and
Ornstein-Uhlenbeck processes, whose spectra are all included into
-$\mathbb{Z}_+$. As a by-product, we offer a clarification of an intertwining
relation found in Biane [2] between the Yule and the Ornstein-Uhlenbeck
processes.
