On third homologies of groups and of quandles via the Dijkgraaf-Witten invariant and Inoue-Kabaya map

Takefumi Nosaka

We propose a simple method to produce quandle cocycles from group cocycles, as a modification of Inoue-Kabaya chain map. We further show that, in respect to "universal central exte…

Homotopical interpretation of link invariants from finite quandles

Takefumi Nosaka

This paper demonstrates a topological meaning of quandle cocycle invariants of links with respect to finite connected quandles X, from a perspective of homotopy theory: Specifica…
