概要
Under some settings for the Milnor invariants, K. Orr constructed a link-invariant which lies in a 3-th homotopy group. I generalized the invariant compatible with every link representation. In this talk, I introduce the construction, and future plan, and some of recent results. Here the key wards are solvable concordance group and higher Massey products.
