Brown representability often fails for homotopy categories of complexes
Published online by Cambridge University Press: 07 November 2011
Abstract
We show that for the homotopy category K(Ab) of complexes of abelian groups, both Brown representability and Brown representability for the dual fail. We also provide an example of a localizing subcategory of K(Ab) for which the inclusion into K(Ab) does not have a right adjoint.
