Ricci-flat supertwistor spaces

چکیده
We show that supertwistor spaces constructed as a Kähler quotient of a hyperkähler cone (HKC) with equal numbers of bosonic and fermionic coordinates are Ricci-flat, and hence, Calabi-Yau. We study deformations of the supertwistor space induced from deformations of the HKC. We also discuss general infinitesimal deformations that preserve Ricci-flatness.

0 On supersymmetric solutions in D = 11 supergravity with Ricci - flat internal spaces
An introduction to supersymmetric (SUSY) solutions defined on the product of Ricci-flat spaces in D = 11 supergravity is presented. The paper contains some background information: (i) decomposition relations for SUSY equations and (ii) 2 −k-splitting theorem that explains the appearance of N = 2 −k fractional supersym-metries. Examples of M 2 and M 5 branes on the product of two Ricci-flat spac...
متن کاملLocally conformal flat Riemannian manifolds with constant principal Ricci curvatures and locally conformal flat C-spaces
It is proved that every locally conformal flat Riemannian manifold all of whose Jacobi operators have constant eigenvalues along every geodesic is with constant principal Ricci curvatures. A local classification (up to an isometry) of locally conformal flat Riemannian manifold with constant Ricci eigenvalues is given in dimensions 4, 5, 6, 7 and 8. It is shown that any n-dimensional (4 ≤ n ≤ 8)...
متن کاملResolutions of non-regular Ricci-flat Kähler cones
We present explicit constructions of complete Ricci-flat Kähler metrics that are asymptotic to cones over non-regular Sasaki-Einstein manifolds. The metrics are constructed from a complete Kähler-Einstein manifold (V, gV ) of positive Ricci curvature and admit a Hamiltonian two-form of order two. We obtain Ricci-flat Kähler metrics on the total spaces of (i) holomorphic C/Zp orbifold fibrations...
متن کاملGeneralized pp-wave solutions on product of Ricci-flat spaces
A multidimensional gravitational model with several scalar fields and fields of forms is considered. A wide class of generalized pp-wave solutions defined on a product of n + 1 Ricci-flat spaces is obtained. Certain examples of solutions (e.g. in supergravitational theories) are singled out. For special cone-type internal factor spaces the solutions are written in Brinkmann form. An example of ...
متن کاملul 2 00 4 Harmonic homogeneous manifolds of nonpositive curvature
A Riemannian manifold is called harmonic if its volume density function expressed in polar coordinates centered at any point of the manifold is radial. Flat and rank-one symmetric spaces are harmonic. The converse (the Lichnerowicz Conjecture) is true for manifolds of nonnegative scalar curvature and for some other classes of manifolds, but is not true in general: there exists a family of homog...
