Homotopy, Δ-equivalence and concordance for knots in the complement of a trivial link

open access: yesTopology and Its Applications, 2010
Link-homotopy and self Δ-equivalence are equivalence relations on links. It was shown by J. Milnor (resp. the last author) that Milnor invariants determine whether or not a link is link-homotopic (resp. self Δ-equivalent) to a trivial link. We study link-

The concordance invariant tau in link grid homology [PDF]

open access: yesAlgebraic and Geometric Topology, 2018
We introduce a generalization of the Ozsváth-Szabó τ-invariant to links by studying a filtered version of link grid homology. We prove that this invariant remains unchanged under strong concordance and we show that it produces a lower bound for the slice
