There is a +-Ramsey MAD family

  • Osvaldo GuzmánEmail author


We answer an old question of Michael Hrušák by constructing a +-Ramsey MAD family without the need of any additional axioms beyond ZFC. We also prove that every Miller-indestructible MAD family is +-Ramsey; this improves a result of Michael Hrušák.
