I'm writing about the paper "A solution to Dilworth's congruence lattice problem" that you submitted to JAMS.
All the referees agreed that your paper represented one of the most important developments in lattice theory in many years. On the basis of this, I brought to the paper to the full editorial board at our recent annual meeting.
After some discussion, the board finally came to the conclusion that the paper was not a good match for JAMS. The feeling was that the problem that the paper solves did not have the sort of interaction with other branches of mathematics that is typical of JAMS papers. Therefore I must return the paper now so that you can make other arrangements for its publication.
I'm sorry not to have better news to report, but as you may know JAMS publishes only 1000 pages a year, so we get many excellent submissions that we are unable to accept. I also apologize for the delay in the decision -- besides the fact that the main referee report took a long time to arrive, I also felt that it was important for the full editorial board to discuss this case.
Sincerely,
