Fox pairings of Poincaré duality groups

Takefumi Nosaka

This paper develops the study of Fox pairings of a group $G$ from the viewpoint of group cohomology. We compute some cohomology groups of Fox pairings of $G$ , where $G$ admits a Po…

Bilinear-form invariants of Lefschetz fibrations over the 2-sphere

Takefumi Nosaka

We introduce invariants of Hurwitz equivalence classes with respect to arbitrary group $G$ . The invariants are constructed from any right $G$ -modules $M$ and any $G$ -invariant bili…
