On the Gauss-Epple homomorphism of the braid group , and generalizations to Artin groups of crystallographic type

Joshua Guo, Kevin Chang

In this paper, we introduce a broad family of group homomorphisms that we name the Gauss-Epple homomorphisms. In the setting of braid groups, the Gauss-Epple invariant was original…
