ON WEAKLY m−PROJECTIVELY SYMMETRIC MANIFOLDS
for arbitrary vector fieldsX, Y , Z, U , V ∈ χ(Mn), whereD denotes the operator of covariant differentiation with respect to the Riemannian metric g and A, B, C, D and E are 1−forms (not simultaneously zero). The 1−forms are called the associated 1−forms of the manifold and an n−dimensional manifold of this kind is denoted by (WS)n. Tamassy and Binh [14] further studied weakly symmetric Sasakia...
متن کاملConformally flat metrics on 4-manifolds
We prove that for each closed smooth spin 4-manifold M there exists a closed smooth 4-manifold N such that M#N admits a conformally flat Riemannian metric.
متن کاملGeometric Inequalities on Locally Conformally Flat Manifolds
In this paper, we are interested in certain global geometric quantities associated to the Schouten tensor and their relationship in conformal geometry. For an oriented compact Riemannian manifold (M,g) of dimension n > 2, there is a sequence of geometric functionals arising naturally in conformal geometry, which were introduced by Viaclovsky in [29] as curvature integrals of Schouten tensor. If...
متن کاملTwistors in Conformally Flat Einstein Four-manifolds
Abstract. This paper studies the two-component spinor form of massive spin2 potentials in conformally flat Einstein four-manifolds. Following earlier work in the literature, a nonvanishing cosmological constant makes it necessary to introduce a supercovariant derivative operator. The analysis of supergauge transformations of primary and secondary potentials for spin 3 2 shows that the gauge fre...
متن کاملCauchy Kernels for some Conformally Flat Manifolds
Here we will consider examples of conformally flat manifolds that are conformally equivalent to open subsets of the sphere S. For such manifolds we shall introduce a Cauchy kernel and Cauchy integral formula for sections taking values in a spinor bundle and annihilated by a Dirac operator, or generalized Cauchy-Riemann operator. Basic properties of this kernel are examined, in particular we exa...
