Higher order Kirk invariants of link maps
Benjamin Audoux, Jean-Baptiste Meilhan, Akira Yasuhara
We define numerical link-homotopy invariants of link maps of any number of components, which naturally generalize the Kirk invariant. The Kirk invariant is a link-homotopy invarian…

k-reduced groups and Milnor invariants
Benjamin Audoux, Jean-Baptiste Meilhan, Akira Yasuhara
We characterize, in an algebraic and in a diagrammatic way, Milnor string link invariants indexed by sequences where any index appears at most times, for any fixed . Th…
