Topic: Invariant Distances on Legendrian Spaces
Speaker: Pierre-Alexandre Arlove

I will begin by motivating the study of invariant distances on spaces of Legendrians. I will then discuss two main results:(a) the construction of a new unbounded invariant distance on the universal cover of many Legendrian isotopy classes ;(b) the discreteness of any invariant distance on Legendrian isotopy classes.
In particular, we will see that (a) arises from contact rigidity, whereas (b) follows from contact flexibility.
