We study the notion of orderability of isotopy classes of Legendrian submanifolds and their
universal covers, with some weaker results concerning spaces of contactomorphisms. Our …

We show that there exist contact isotopies of the standard contact sphere whose time-1
maps do not have any translated points which are optimally close to the identity in the …

Let Y be a prequantization bundle over a closed spherically monotone symplectic manifold
Σ. Adapting an idea due to Diogo and Lisi, we study a split version of Rabinowitz Floer …

Using SFT techniques, Eliashberg, Kim and Polterovich (2006) proved that if $\pi R_2^ 2\leq
K\leq\pi R_1^ 2$ for some integer $ K $ then there is no contact squeezing in $\mathbb …

For certain contact manifolds admitting a 1-periodic Reeb flow we construct a conjugation-
invariant norm on the universal cover of the contactomorphism group. With respect to this …

We relate non-orderability in contact topology to shortening in the contact Hofer norm.
Combined with considerations of open books, this provides many new examples of non …

We use generating function techniques developed by Givental, Théret and ourselves to
deduce a proof in ℂ P d of the homological generalization of Franks theorem due to …

This article is concerned with the Rabinowitz Floer homology of negative line bundles. We
construct a refined version of Rabinowitz Floer homology and study its properties. In …

In this paper, we construct a sequence $(c_k) _ {k\in\mathbb {N}} $ of symplectic capacities
based on the Chiu-Tamarkin complex $ C_ {T,\ell} $, a $\mathbb {Z}/\ell $-equivariant …
