چکیده
Two-sided conformally recurrent 4-dimensional self-dual spaces are considered. It is shown that such equipped with nonexpanding congruences of null strings. The general structure weak hyperheavenly given. Finally, the metrics Petrov-Penrose type $[D] x [-]$ presented.

متن کاملGrassmannians of Two-sided Vector Spaces
Let k ⊂ K be an extension of fields, and let A ⊂ Mn(K) be a k-algebra. We study parameter spaces of m-dimensional subspaces of Kn which are invariant under A. The space FA(m, n), whose R-rational points are A-invariant, free rank m summands of Rn, is well known. We construct a distinct parameter space, GA(m, n), which is a fiber product of a Grassmannian and the projectivization of a vector spa...
متن کاملDuals of Simple Two-sided Vector Spaces
Let K be a perfect field and let k ⊂ K be a subfield. In [4, Theorem 3.2], left finite dimensional simple two-sided k-central vector spaces over K were classified by arithmetic data associated to the extension K/k. In this paper, we continue to study the relationship between simple two-sided vector spaces and their associated arithmetic data. In particular, we determine which arithmetic data co...

متن کاملKaluza-klein Reduction of Conformally Flat Spaces
A “conformal tensor” is constructed from the metric tensor gMN (or Vielbein e A M ) and is invariant against Weyl rescaling gMN → egMN (or eM → eeM ). Moreover, it vanishes if and only if the space is conformally flat, gMN = e ηMN (or e A M = eδ M ). In dimension four or greater the conformal tensor is the Weyl tensor. In three dimensions the Weyl tensor vanishes identically, while the Cotton t...
