Subject: for the list Date: Fri, 10 Aug 2001 11:50:49 -0400 (EDT) From: "W. Stephen Wilson" To: dmd1@lehigh.edu Don, for the list, Steve Hopf ring calculations: I have been writing computer programs for calculating with Hopf rings, particularly those associated with BP. My programs are not well organized yet or documented, but if someone had some computations in mind which they would like to see done, please contact me and maybe I can modify my programs relatively easily to help you out. To give a feel for what can be done with them, my interest has been in computing the kernel of maps of connected Morava K-theory of spaces in the BP Omega spectrum which come from stable BP maps. I have obtained very little useful information but perhaps some insight. However, being able to do this at all suggest that there are lots of other things which have been done. Steve W.
