• Abstract:
  We prove that if the sequence \langle k_n:1 \le n < \omega\rangle contains a so-called gap then the sequence \langle S^{\aleph_n}_{\aleph_{k_n}}:1 \le n < \omega\rangle of stationary sets is not mutually stationary, provided that k_n<n for every n \in \omega. We also prove a sufficient condition for being singular Jonsson cardinals.
