Gromov's non-squeezing theroem
WebDec 25, 2009 · Abstract. As has been known since the time of Gromov’s Non-squeezing Theorem, symplectic embedding questions lie at the heart of symplectic geometry. After surveying some of the most important ways of measuring the size of a symplectic set, these notes discuss some recent developments concerning the question of when a 4 … WebAug 9, 2024 · The classical proof of the non-squeezing theorem makes use of the geometric setting of ‘least energy’ to rule out (1) nodal curves as well as (2) isotropy (due to multiple covers), so that only (3) the differentiability challenge is present. The latter is resolved by finding a regular choice of J with φ∗ J = Jst.

WebThe motivation for this thesis comes from Gromov’s Non-squeezing theorem [G], which is the classical mechanical counterpart of Heisenberg’s uncertainty principle. Letting Bk(r) denote the k-dimensional open ball of radius r, the Non-squeezing theorem asserts that B2n(1 + ǫ) with its standard symplectic structure cannot be
