TitleOn diffeomorphisms over non-orientable surfaces standardly embedded in the 4-sphere
Abstract
For a non-orientable closed surface standardly embedded in the 4-sphere, a diffeomorphism over this surface is extendable if and only if this diffeomorphism preserves the Guillou-Marin quadratic form of this embedded surface.
