Abstract
We prove one deformation theoretic extension of the Gromov non-squeezing phenomenon to \({{\,\textrm{lcs}\,}}\) structures, or locally conformally symplectic structures, which suitably generalize both symplectic and contact structures. We also conjecture an analogue in \({{\,\textrm{lcs}\,}}\) geometry of contact non-squeezing of Eliashberg–Polterovich and discuss other related questions.
