Given a compact symplectic manifold whose symplectic form has integer periods, one associates to it a dg category based on the microlocal analysis according to Kashiwara-Schapira.

…we try to explain how standard symplectic techniques, for instance, generating function, capacities, symplectic homology, etc., are elegantly packaged in the language of sheaves as well as related intriguing sheaf operators. In addition, many concepts developed in Tamarkin category theory are natural generalizations of persistent homology theory…

In this paper we solve a contact non-squeezing conjecture proposed by Eliashberg, Kim and Polterovich. Let BR be the open ball of radius RR in 2n\mathbb{R}^{2n} and let 2n×S 1\mathbb{R}^{2n}\times S^1 be the prequantization space equipped with the standard contact structure. Following Tamarkin’s idea, we apply microlocal category methods to prove that if RR and rr satisfy 1πr 2<πR 21\leq \pi r^2 \lt \pi R^2, then it is impossible to squeeze the contact ball B R×S 1B_R\times S^1 into B r×S 1B_r\times S^1 via compactly supported contact isotopies.
