A nonisoparametric hypersurface with constant principal curvatures

Differential Geometry 2019-03-11 v1

Abstract

In this note we construct an explicit example of a (compact) conformally flat Riemannian manifold which admits a totally geodesic foliation of codimension one with no isoparametric leaves. This answers negatively the question: is every hypersurface with constant principal curvatures isoparametric?
