Surfaces with parallel mean curvature vector in \(P^ 2(\mathbb C)\) (Q1911161)

The author studies 2-dimensional non-minimal submanifolds with parallel mean curvature vector in the complex projective plane \(P^2(\mathbb C)\). He gives a method of constructing such submanifolds and proves a theorem determining isometric immersions with parallel mean curvature vector field of Riemannian 2-dimensional manifolds with constant Gaussian curvature into \(P^2(\mathbb C)\).
