Glaring error

[edit]

We supposedly have:

How can we take ? Cohomology is contravariant, so . This mistake renders the statement of the conjecture totally non-sensical.

In the linked seminar notes there ist the same mistake. I think, x should be in H^{n-4i}(BG). This makes most sense in view of how a result of Novikov is shown to be a special case of the Novikov conjecture the seminar notes, I think. --Cardano 13:09, 12 October 2006 (UTC)[reply]

That link (as well as the mistake) was on the original page, created a year ago. Thank you, anonymous person. And Cardano you're right - the conjecture is stated in the referreed article, page 195 at http://www.maths.ed.ac.uk/~aar/books/wall1.pdf Orthografer 15:16, 12 October 2006 (UTC)[reply]
