Rigidity of Three-Dimensional Self-Shrinkers with Constant Norm of the Second Fundamental Form

Abstract

Let X:M3→R4 be a complete, connected self-shrinker without boundary, and suppose that the squared norm S of its second fundamental form is constant. We prove that S=0 or S=1. Accordingly, the image is a hyperplane through the origin or a generalized cylinder 𝕊k(√k)×R3−k, 1≤ k≤3, and the immersion is a Riemannian covering onto its image.
