TitleQuandle and link-homotopy
Abstract
In this talk, we define quasi-triviality of quandles. We show that a quandle cocycle invariant derived from a 2-cocycle of a quasi-trivial quandle is a link-homotopy invariant if the 2-cocycle satisfies a certain condition. It means that we have a lot of numerical link-homotopy invariants.
