Covering link calculus and iterated Bing doubles
Jae Choon Cha, Taehee Kim
We give a new geometric obstruction to the iterated Bing double of a knot being a slice link: for n>1 the (n+1)-st iterated Bing double of a knot is rationally slice if and only if…

Structure of the string link concordance group and Hirzebruch-type invariants
Jae Choon Cha
We employ Hirzebruch-type invariants obtained from iterated p-covers to investigate concordance of links and string links. We show that the invariants naturally give various group…

Link concordance, homology cobordism, and Hirzebruch-type defects from iterated p-covers
Jae Choon Cha
We obtain new invariants of topological link concordance and homology cobordism of 3-manifolds from Hirzebruch-type intersection form defects of towers of iterated p-covers. Our in…
