Homogeneity of infinite dimensional isoparametric submanifoldsErnst Heintze and Xiaobo LiuReview from Zentralblatt MATH: The main result of the paper is the following remarkable Theorem. Let $M$ be a complete, connected, irreducible isoparametric submanifold in a Hilbert space $V$. Assume that the set of all the curvature normals of $M$ at some point is not contained in any affine line. Then, $M$ is extrinscially homogeneous in the Hilbert space $V$. The finite dimensional case of this theorem was first proved by the reviewer [Ann. Math., II. Ser. 133, 429-446 (1991; Zbl 0845.53040)]. It is very likely that the main result of the paper under review can be used to prove a homogeneity theorem for equifocal submanifolds.
