A geometric proof that boundary links are homotopically trivial
A boundary link is a link in \(S^ 3\) whose components bound disjoint surfaces (compact and oriented). This paper gives a proof that such links are homotopic to a trivial link which uses only elementary geometric facts about links and surfaces. In particular it does not make any use of the Milnor \({\bar \mu}\) invariants.
