On flat translated chains of contactomorphisms of and
Marco Mazzucchelli, Sheila Sandon
The paper defines flat translated chains of contactomorphisms and proves that any non‑trivial compactly supported contactomorphism of ℝ^{2n+1} or ℝ^{2n}×S^1 isotopic to the identit…

Non-squeezing and other global rigidity results in locally conformal symplectic geometry
Mélanie Bertelson, Pranav Chakravarthy, Sheila Sandon
Using generating functions quadratic at infinity for Lagrangian submanifolds of twisted cotangent bundles, we define spectral selectors for compactly supported lcs Hamiltonian diff…

Contact non-squeezing at large scale via generating functions
Maia Fraser, Sheila Sandon, Bingyu Zhang
Using SFT techniques, Eliashberg, Kim and Polterovich (2006) proved that if for some integer then there is no contact squeezing in $\mathbb{R}^{2n…
