A family of freely slice good boundary links
Jae Choon Cha, Min Hoon Kim, Mark Powell
We show that every good boundary link with a pair of derivative links on a Seifert surface satisfying a homotopically trivial plus assumption is freely slice. This subsumes all pre…

A ribbon obstruction and derivatives of knots
JungHwan Park, Mark Powell
We define an obstruction for a knot to be Z[Z]-homology ribbon, and use this to provide restrictions on the integers that can occur as the triple linking numbers of derivative link…

Four-manifolds up to connected sum with complex projective planes
Daniel Kasprowski, Mark Powell, Peter Teichner
We show that closed, connected 4-manifolds up to connected sum with copies of the complex projective plane are classified in terms of the fundamental group, the orientation charact…
