Subject: A question for the list From: Jesus Gonzalez Date: Tue, 9 Aug 2005 22:12:40 -0500 (MDT) A question for the list: It is known that the Eilenberg-MacLane space K(Z/2^e,2) is uglier than expected in the sense that it has infinite BP-projective dimension (at least for e>1). Yet: is it true that multiplication by v_2 is monic? If one replaces K(Z/2^e,2) by K(Z/2^e,1) \times K(Z/2^e,1), is it known: 1. if v_2 multiplication is monic ? 2. hom.dim = 2 ?? Jesus Gonzalez
