Abstract

We study isometric immersions f:MnRn+1f: M^{n}\to \mathbb{R}^{n+1} into Euclidean space of dimension n+1n+1 of a complete Riemannian manifold of dimension nn on which a compact connected group of intrinsic isometries acts with principal orbits of codimension one. We give a complete classification if either n3n\geq 3 and MnM^n is compact or if n5n\geq 5 and the connected components of the flat part of MnM^n are bounded. We also provide several sufficient conditions for ff to be a hypersurface of revolution.
