This paper describes the relationship between the first non‐vanishingMilnor invariantsof a classical link and the intersection invariant of atwisted Whitney tower. This is a certain 2‐complex in the 4‐ball, built from immersed disks bounded by the given link in the 3‐sphere together with finitely many ‘layers’ of Whitney disks.Theintersection invariantis a higher‐order generalization of the intersection number between two immersed disks in the 4‐ball, well known to give the linking number of the link on the boundary, which measures intersections among the Whitney disks and the disks bounding the given link, together with information that measures the twists (framing obstructions) of the Whitney disks.This interpretation of Milnor invariants as higher‐order intersection invariants plays a key role in our classifications [J. Conant, R. Schneiderman and P. Teichner, ‘Higher‐order intersections in low‐dimensional topology’,Proc. Natl Acad. Sci. USA108 (2011) 8131–8138; J. Conant, R. Schneiderman and P. Teichner, ‘Whitney tower concordance of classical links’,Geom. Topol.16 (2012) 1419–1479] of both the framed and twisted Whitney tower filtrations on link concordance. Here, we show how to realize thehigher‐order Arf invariants, which also play a role in the classifications, and derive new geometric characterizations of links with vanishing length at most 2kMilnor invariants.
