On Lagrangian barriers and applications of Non-Squeezing
Abstract: In this note we show the existence of Lagrangian barriers in a certain class of domains in $\mathbb{R}{2n}$, including dual Lagrangian products and some ``sufficiently" round domains. Many of these results come as applications of the Non-Squeezing Theorem. We also give a new interesting application of the Non-Squeezing Theorem and the Symplectic Camel Theorem.
