Addendum and correction to: Homology cylinders: an enlargement of the mapping class group
In a previous paper [Homology cylinders: an enlargement of the mapping
class group, Algebr. Geom. Topol. 1 (2001) 243--270,
arXiv:math.GT/0010247], a group H_g of homology cylinders over the
oriented surface of genus g is defined. A filtration of H_g is
defined, using the Goussarov-Habiro notion of finite-type. It is
erroneously claimed that this filtration essentially coincides with
the relative weight filtration. The present note corrects this error
and studies the actual relation between the two filtrations.
