Abstract: We investigate a diffusion problem in the group 
of Cκ symplectic diffeomorphisms of the annulus 𝔸2,with compact support contained in 𝕋2×I2,where I ⊂ ℝ is a fixed interval containing [0, 1] in its interior. We endow κ with the uniform Cκ topology.
Let (θ, r) be the usual angle-action coordinates on 𝔸2. We say that a diffeomorphism in κ satisfies the ...
