Abstract
Let and be commuting diffeomorphisms of the cylinder that are, respectively, close to and , where is non-degenerate and is Diophantine. Using the KAM iterative scheme for the group action we show that and are simultaneously -linearizable if has the intersection property (including the exact symplectic maps) and satisfies a semi-conjugacy condition. We also provide examples showing necessity of these conditions. As a consequence, we get local rigidity of certain class of -actions on the cylinder, generated by commuting twist maps.
