Surfaces in the complex projective plane and their mapping class groups

Susumu Hirose

Abstract. An orientation preserving diffeomorphism over a surface embedded in a 4-manifold is called extendable, if this diffeomorphism is a restriction of an orientation preserving diffeomorphism on this 4-manifold. In this paper, we investigate conditions for extendability of diffeomorphisms over surfaces in the complex projective plane.

Keywords. Knotted surface, plane curve, mapping class group, spin mapping class group
