Abstract.
The Wall surgery obstruction groups have two interesting geometrically defined subgroups, consisting of the surgery obstructions between closed manifolds, and the inertial elements.
We show that the inertia group and the closed manifold subgroup
are equal in dimensions
, for any finitely-presented group
and any orientation character
. This answers a question raised in 1980.
