Let $X$ be a symplectic manifold, and let $g_0,g_1:X\rightarrow X$ be symplectomorphisms. The maps $(g_0)_*$ and $(g_1)_*$ are induced on the groups $SH_{\bullet}^M(Y,X)$ associate…

Let $(M,\omega)$ be a closed connected symplectic manifold. Denote by $\operatorname{Symp}(M,\omega)$ the group of symplectomorphisms, by $\operatorname{Symp}_0(M,\omega)$ its iden…

A flexible Weinstein structure is a Weinstein structure whose underlying Weinstein domain is flexible, and a compactly supported symplectomorphism is a symplectomorphism equal to t…

Let $\Phi$ be the homomorphism from automorphisms of the Weyl algebra to polynomial symplectomorphisms constructed by reduction modulo an infinite prime, restriction to centers, in…
