Caustics of Lagrangian homotopy spheres with stably trivial Gauss map

Daniel Alvarez-Gavela, David Darrow

For each positive integer $n$ , we give a geometric description of the stably trivial elements of the group $π_{n} U_{n} / O_{n}$ . In particular, we show that all such elements admit repres…

A Legendrian Turaev torsion via generating families

Daniel Alvarez-Gavela, Kiyoshi Igusa

We introduce a Legendrian invariant built out of the Turaev torsion of generating families. This invariant is defined for a certain class of Legendrian submanifolds of 1-jet spaces…
