A surface in a smooth 4-manifold is called flexible if, for any diffeomorphism φ{symbol} on the surface, there is a diffeomorphism on the 4-manifold whose restriction on the surface is φ{symbol} and which is isotopic to the identity. We investigate a sufficient condition for a smooth 4-manifold M to include flexible knotted surfaces, and introduce a local operation in simply connected 4-manifolds for obtaining a flexible knotted surface from any knotted surface.
