Corrigendum to "Nonabelian free group actions: Markov processes, the   Abramov- Rohlin formula and Yuzvinskii's formula"
  We correct an error in the proof of the Rohlin-Abramov addition formula for free group actions and point out errors in the proof of Yuzvinskii's addition formula. It is not known if the latter are fixable.
