Legendrians with vanishing Shelukhin-Chekanov-Hofer metric (2301.07575v2)
Published 18 Jan 2023 in math.SG
Abstract: We show that the Legendrian lift of an exact, displaceable Lagrangian has vanishing Shelukhin-Chekanov-Hofer pseudo-metric by lifting an argument due to Sikorav to the contactization. In particular, this proves the existence of such Legendrians, providing counterexamples to a conjecture of Rosen and Zhang.
