Concordance of links with identical Alexander invariants
Jae Choon Cha, Stefan Friedl, Mark Powell
J. Davis showed that the topological concordance class of a link in the 3-sphere is uniquely determined by its Alexander polynomial for 2-component links with Alexander polynomial…

Covering link calculus and the bipolar filtration of topologically slice links
Jae Choon Cha, Mark Powell
The bipolar filtration introduced by T. Cochran, S. Harvey, and P. Horn is a framework for the study of smooth concordance of topologically slice knots and links. It is known that…

A second order algebraic knot concordance group
Mark Powell
We define an algebraic group comprising symmetric chain complexes which captures the first two stages of the Cochran-Orr-Teichner solvable filtration of the knot concordance group…
