This invention relates to substrates and articles of manufacture incorporating a fluoropolymer primer coating. The primer coating comprises a copolymer of ethylene and a halogenated comonomer selected from the group consisting of tetrafluoroethylene, chlorotrifluoroethylene and mixtures thereof and 0 to 10 mol percent of an additional monomer selected from the group consisting of 3,3,3-trifluoro-2-trifluoromethyl propene, a vinyl monomer which is free of telogenic activity and which provides a…

Abstract In this sequel to an earlier article, employing more commutative algebra than previously, we show that an isoparametric hypersurface with four principal curvatures and multiplicities (3,4)

Let M be an isoparametric hypersurface in the sphere S n with four distinct principal curvatures. Munzner showed that the four principal curvatures can have at most two distinct multiplicities m1 ,m
ISOPARAMETRIC HYPERSURFACES WITH FOUR PRINCIPAL CURVATURES, III
The classification work [5], [8] left unsettled only those anomalous isoparametric hypersurfaces with four principal curvatures and multiplicity pair {4, 5}, {6, 9}, or {7, 8} in the sphere. By
A NOTE ON THE PAPER ”ISOPARAMETRIC HYPERSURFACES WITH FOUR PRINCIPAL CURVATURES”
In [6], employing commutative algebra, we showed that if the number of principal curvatures is 4 and if the multiplicities m1 and m2 of the principal curvatures satisfy m2 ≥ 2m1 − 1, then the
Ideal theory and classification of isoparametric hypersurfaces
The classification of isoparametric hypersurfaces with four principal curvatures in the sphere interplays in a deep fashion with commutative algebra, whose abstract and comprehensive nature might
Isoparametric and Dupin Hypersurfaces
A hypersurface M n 1 in a real space-form R n , S n or H n is isoparametric if it has constant principal curvatures. For R n and H n , the classification of isoparametric hypersurfaces is complete
Isoparametric hypersurfaces with four principal curvatures, IV
We prove that an isoparametric hypersurface with four principal curvatures and multiplicity pair $(7,8)$ is either the one constructed by Ozeki and Takeuchi, or one of the two constructed by Ferus,
Topology of Dupin hypersurfaces with six distinct principal curvatures
Abstract. Let M be a Dupin hypersurface in the unit sphere $S^{n+1}$ with six distinct principal curvatures. We will prove in the present paper that M is either diffeomorphic to \$SU(2)\times
Multiplicities of Dupin hypersurfaces
Abstract.All known examples of isoparametric hypersurfaces of spheres are of the following two types:¶(1) The homogeneous examples, which are principal orbits of isotropy representations of symmetric
Taut and Dupin Submanifolds
This is a survey of the closely related fields of taut submanifolds and Dupin submanifolds of Euclidean space. The emphasis is on stating results in their proper context and noting areas for future

Introduction. This paper is a continuation of Part I [13]. In the first half of the present paper, we study the homogeneous isoparametric hyper surf aces in spheres. Every homogeneous hyper surf ace
