Subject: possible question for the list From: Jack Morava Date: Fri, 1 Jun 2007 08:02:30 -0400 (EDT) I suspect the answer to this question is known (but not by me!): What is the (Ochanine-Landweber-Ravenel-Stong) elliptic genus of the quaternionic projective space HP_n? [Its A^-genus HP_n vanishes (if n > 0), for example because it admits a nontrivial circle action.] Help, go-to's, or references would be very much appreciated. Best, Jack
